Goals for Improvement

• Use Haifa’s highest-purity macronutrient sources:

  • Multi-K® Potassium Nitrate (13-0-46)

  • Haifa MKP (0-52-34)

  • Haifa MAP (12-61-0)

  • Haifa Cal if needed for Ca supplementation.

• Use Boca Hydro chelated micros for maximum availability:

  • Fe DTPA or EDDHA (for strawberries, better than EDTA above pH 6.5)

  • Zn EDTA 14%

  • Mn EDTA 14%

  • Cu EDTA 14%

  • Boric Acid (high purity)

  • Sodium Molybdate

• Improve solubility, pH stability, and uptake in drip/fertigation.

• Reduce ammonium levels slightly to limit vegetative excess.

Do you want me to do that next?

Alright — let’s build a precise recipe for 100 lbs of the improved Boca Hydro Strawberry Fertilizer using Haifa macronutrients + your Boca Hydro chelated micronutrients.

We'll match the target guaranteed analysis from my optimized formula above (8‑12‑32 + micros), keep solubility perfect for drip/fertigation, and balance nitrate/ammonium for strawberries.

Step 1 — Target Formula for 100 lbs

We want the final 100 lbs of dry fertilizer to hit:

That leaves ~45.8 lbs of macronutrient carriers + fillers.

Step 2 — Ingredient Selection & Analysis

We'll use Haifa nutrients for macros and Boca Hydro micros:

Step 3 — Calculate Macro Ingredients

A. Potassium Sources (33 lbs K₂O needed)

We’ll split between Multi-K and MKP for best solubility:

• Multi-K: ~46% K₂O → 50% of K from here = 23 lbs Multi-K → gives 10.6 lbs K₂O and 3 lbs N.

• MKP: 34% K₂O → ~26 lbs MKP → gives 8.8 lbs K₂O and 13.5 lbs P₂O₅.

So far:

• K₂O ≈ 10.6 + 8.8 = 19.4 lbs (we need 13.6 lbs more K₂O).

We’ll make up the rest with more Multi-K:

• Extra 29 lbs Multi-K total → 13.3 lbs K₂O and 3.8 lbs N.

Final Multi-K = 29 lbs
Final MKP = 26 lbs

B. Phosphorus Sources (12 lbs P₂O₅ needed)

• MKP (26 lbs) → 13.5 lbs P₂O₅ ✅

• That slightly overshoots but improves bloom quality, acceptable.

We don’t need MAP for P, but we’ll add a small MAP dose just for ammonium balance.

C. Nitrogen Sources (8 lbs N needed)

Currently from Multi-K (29 lbs):

• 3.8 lbs N nitrate.

We want ~90% nitrate, 10% ammonium, so:

• Add 3 lbs MAP → 0.36 lbs ammonium + 0.36 lbs nitrate.

• Add 1.5 lbs Ammonium Sulfate → 0.3 lbs ammonium.

This gives:

• Nitrate N ≈ 3.8 + 0.36 = 4.16 lbs

• Ammonium N ≈ 0.36 + 0.3 = 0.66 lbs

• Remaining N from small MAP boost = balance to 8 lbs total.

Step 4 — Micronutrient Weights

Step 5 — Final 100 lb Formula

Total ≈ 100 lbs

Step 6 — Next Step

I recommend we now create:

• A 1:100 fertigation dosing chart for strawberries,

• Including ppm targets for N, P, K, and micros,

• With conversions to grams per gallon, oz per gallon, tablespoons, and ml concentrate per gallon.

Do you want me to make that next? That’ll make this formula fully ready for your Boca Hydro label.

Got it — you’re right.
The original Boca Hydro Strawberry Fertilizer you sent didn’t include calcium (Ca) or magnesium (Mg), but for a better, high‑performance strawberry formula, we should include them. Strawberries are high calcium feeders, and magnesium is critical for photosynthesis and fruit color.

If you want this to beat the original formula, we’ll need to integrate Haifa Cal (Calcium Nitrate) and Magnesium Nitrate or Magnesium Sulfate, depending on how you want to handle solubility and pH.

Let me revise the formula to include Ca + Mg while keeping the target NPK and micros the same.

Step 1 — Updated Nutritional Targets

For optimal strawberry production under drip/fertigation, most commercial programs target:

This will make it far superior to the original.

Step 2 — Add Calcium & Magnesium Sources

We’ll use Haifa Cal (Calcium Nitrate 15.5-0-0 + 26% Ca) and Magnesium Nitrate (11% N + 9.5% Mg). These are fully water‑soluble and compatible with Haifa MKP, Multi‑K, and your Boca Hydro micros.

Step 3 — Revised Ingredient Weights (100 lbs Batch)

Here’s the new optimized recipe using Haifa + Boca Hydro materials:

Total ≈ 100 lbs

Step 4 — Why This Is Better

Step 5 — Next Step

To make this formula fully usable, I can give you:

• Exact ppm breakdown per 1 g/L

• 1:100 fertigation dosing chart

• Grams, ounces, teaspoons, tablespoons per gallon

• A printable one-page Boca Hydro PDF feeding guide with your logo.

Do you want me to generate the fertigation dosing table + ppm targets next so we can finalize the improved strawberry formula? That’ll make it ready for your labels and Amazon listings.

Got it ✅ — you want to remove ammonium sulfate entirely and instead use magnesium sulfate (Epsom salt) for the magnesium source and as the filler.
That makes perfect sense for strawberries — lower ammonium is better, and magnesium sulfate is cheap, clean, and fully soluble.

I’ll rebuild the 100 lbs Boca Hydro Strawberry Fertilizer formula accordingly, keeping the same 8‑12‑32 NPK, optimizing for solubility, and using Haifa macronutrients + Boca Hydro micros + magnesium sulfate.

Step 1 — Target Nutrient Profile

Step 2 — Selected Ingredients

Macronutrients (Haifa):

• Multi-K® (13‑0‑46) → K + nitrate

• MKP (0‑52‑34) → P + K

• MAP (12‑61‑0) → P + small ammonium

• Haifa Cal (15.5‑0‑0 + 26% Ca) → Ca + nitrate

• Magnesium Sulfate (Epsom, 9.8% Mg) → Mg source + filler

Micronutrients (Boca Hydro):
Fe DTPA 11%, Zn EDTA 14%, Mn EDTA 14%, Cu EDTA 14%, Boric Acid, Sodium Molybdate.

Step 3 — Final 100 lbs Recipe

Total = 100 lbs

Step 4 — Nutrient Contribution Check

Step 5 — Why This Version Is Better

Next Step

If you want, I can now build you a 1:100 fertigation dosing chart for strawberries using this formula:

• Exact grams per gallon

• ml concentrate per gallon

• ppm targets for N, P, K, Ca, Mg, and micros

• Converted to teaspoons, tablespoons, and ounces

• Ready for a one-page Boca Hydro PDF feeding guide.

Do you want me to prepare that next?
It’ll make the formula field-ready and perfect for your Boca Hydro labels.

I understand exactly what you're trying to do, and you’re right to be cautious here.
If we replace Haifa Cal (calcium nitrate) with Boca Hydro Chelated Calcium and add Sulfate of Potash (SOP, K₂SO₄), we need to think about solubility, compatibility, and chloride-free fertigation safety — especially since strawberries are very sensitive.

Let me break this down step by step.

Step 1 — Why Haifa Cal Precipitates

Haifa Cal = Calcium Nitrate (Ca(NO₃)₂, 26% Ca, 15.5% Nitrate N)

Problem:
When calcium nitrate is combined in the same tank with sulfates or phosphates, it forms insoluble precipitates like:

• Calcium sulfate (gypsum)

• Calcium phosphate
  These settle, clog emitters, and reduce nutrient availability.

Solution Options:

1. Two-tank system → Keep Ca separate. ✅ (Best)

2. Use chelated calcium instead of nitrate Ca. ✅ (Safe in single tank)

3. Or skip Ca in the formula entirely → Provide separately. ⚠️ (Not ideal for strawberries)

Step 2 — Using Boca Hydro Chelated Calcium

Your Boca Hydro Chelated Calcium 14% (EDTA) is completely soluble and does NOT react with sulfates or phosphates, so it’s safe in a single-tank formula.

Benefits:

• No precipitation.

• Chelated Ca stays available even in pH 5.5–7.5 range.

• Fully compatible with SOP, MKP, MAP, MgSO₄, Multi-K, and your Boca Hydro micros.

Downsides:

• Chelated Ca is more expensive per unit Ca than Haifa Cal.

• No nitrate contribution → we must replace that N from elsewhere.

Step 3 — Adding SOP (Sulfate of Potash)

SOP (K₂SO₄, 0‑0‑50 + 18% S) advantages:

• Adds K₂O without adding nitrate.

• Supplies sulfur, which strawberries love.

• Completely soluble and chloride-free.

• Fully compatible with MKP, MAP, MgSO₄, chelated Ca, Multi-K, and micros.

However:
If we use SOP + MKP + Multi-K, we need to balance K carefully to avoid overshooting K₂O.

Step 4 — New Revised Formula Plan

We will:

1. Remove Haifa Cal (no nitrate calcium).

2. Use Boca Hydro Chelated Calcium 14% instead.

3. Add Sulfate of Potash (SOP) to make up for lost K₂O.

4. Slightly increase Multi-K to supply needed nitrate N.

5. Keep magnesium from Magnesium Sulfate.

Step 5 — Updated 100 lbs Formula (Chelated Ca + SOP)

Total: ≈ 100 lbs

Step 6 — Impact of This Change

Step 7 — Recommendation

If you plan to keep this a one-bag, one-tank formula, using Boca Hydro Chelated Ca + SOP is the better option.
It eliminates precipitation risk and adds valuable sulfur, which strawberries need.

However, we’ll need to boost Ca slightly since 6 lbs chelated Ca only gives ~1% Ca.
If you want ~4% Ca, you’ll need ~17 lbs Boca Hydro Chelated Ca — which would drive costs up.

Better Option:

• Keep most Ca separate via Boca Hydro Chelated Calcium as a standalone product (tank B).

• Keep this formula chloride-free, sulfur-rich, and fully compatible in tank A.

If you want, I can prepare two optimized recipes for you:
(1) Single-tank formula using chelated Ca + SOP,
(2) Two-tank fertigation program with higher Ca via a separate stock.

This will also affect ppm dosing targets for strawberries.

Do you want me to build both versions side by side with exact grams per gallon + ppm fertigation tables?
That will make it clear which approach is best for Boca Hydro Strawberry.

Alright ✅ — I’ll finalize your Boca Hydro Strawberry Fertilizer as a single‑bag, fully soluble, one‑tank formula using Boca Hydro Chelated Calcium + SOP + Haifa macronutrients + Boca Hydro micros.
Then, I’ll build a complete dosing guide for all growing styles:

• 1:100 fertigation (drip systems, greenhouse injectors)

• Hydroponics (recirculating / DWC / NFT / aeroponics)

• Pots & containers (soil or coco)

• Soil drench

• Foliar spray

Everything will include grams, ounces, teaspoons, tablespoons per gallon + ppm targets.

Step 1 — Final Single‑Bag Formula (100 lbs)

Total = 100 lbs

✅ Chloride-free
✅ Fully compatible
✅ Single-tank safe
✅ Chelated calcium won’t precipitate

Step 2 — PPM Targets

Step 3 — 1:100 Fertigation (Injector) Dosing

For strawberries, most greenhouses use 1:100 stock solutions:

Formula:

5 oz per gallon stock → inject 1:100 → delivers ~80 ppm N, ~180 ppm K, ~52 ppm P, ~40 ppm Ca, ~20 ppm Mg.

Step 4 — Hydroponics Dosing (Recirculating Systems)

Note: Formula dissolves 100% → no residue in NFT/DWC systems.

Step 5 — Pots & Containers

Step 6 — Soil Drench

Step 7 — Foliar Spray

⚠️ Always spray in early morning or late evening.
⚠️ Add a surfactant if possible.

Step 8 — Next Step

I can now make a one-page printable Boca Hydro Strawberry Feeding Guide PDF with:

• Your logo

• Formula specs + guaranteed analysis

• Complete dosing tables for fertigation, hydroponics, pots, drench, foliar

• PPM chart + EC references

• Professional branding, ready for Amazon, Walmart, and your own site.

Do you want me to generate the PDF feeding guide next?
It’ll match your Boca Hydro style perfectly and be customer-friendly.

Got it ✅ — you want to see a 100 lb version of the Boca Hydro Strawberry Fertilizer formula without chelated calcium, so we can supply calcium separately using calcium nitrate (Haifa Cal) in a second stock tank (Tank B).

This will give us:

• A clean, fully compatible Tank A (strawberry fertilizer without Ca)

• Haifa Cal as Tank B for calcium + nitrate nitrogen

• Maximum solubility + no precipitation issues.

Step 1 — Why Two-Tank is Better for Ca

If we mix calcium nitrate with sulfates (MgSO₄, SOP) or phosphates (MKP, MAP) in the same tank, we get calcium sulfate or calcium phosphate precipitation.

Solution:

• Tank A: NPK + Mg + SOP + all micros (no calcium nitrate here)

• Tank B: Calcium nitrate only

• Both inject at the same ratio (e.g. 1:100 fertigation).

Step 2 — Revised Formula (100 lbs, Ca Removed)

Here’s the updated Tank A formula:

Total: ≈ 100 lbs

Step 3 — Calcium Tank (Separate)

This keeps calcium fully soluble, provides extra nitrate N, and avoids precipitation.

Step 4 — PPM & Ratios After Splitting Ca

From Tank A (Fertilizer Bag):

• N: ~60 ppm

• P: ~52 ppm

• K: ~180 ppm

• Mg: ~20 ppm

• S: ~25 ppm

• Micros: per label

From Tank B (Haifa Cal):

• Ca: Adjustable, usually 40–60 ppm

• Nitrate N: Adds 10–20 ppm extra N depending on rate

Step 5 — Pros & Cons

Step 6 — Best Recommendation

• If you want ultimate customer simplicity:
  → Stay with the single-bag chelated Ca formula I made earlier.
  → Customers only handle one bag, one tank.

• If you want the most cost-effective, professional greenhouse program:
  → Use this 100 lb Ca-free bag + separate Haifa Cal stock.
  → Better for high-volume strawberry fertigation.

If you want, I can now prepare two full fertigation dosing charts side by side:

• Single-bag chelated Ca formula ✅

• Two-tank Ca nitrate program ✅

Both would include:

• Grams, teaspoons, tablespoons, ounces per gallon

• 1:100 fertigation stock mixing

• ppm targets for N, P, K, Ca, Mg, micros

Do you want me to make that full comparison next?
That’ll make it very clear which program is better for Boca Hydro customers.
