Part 3 Give me the damn recipe!
This will be more like a collection of recipes as I design and update them.
PP Simple
PP Simple
Polyphosphate simple is a minimized recipe. It uses the fewest number of fertilizers that still meet reasonably good targets.
Makes 250 gallons (approx 1000 Liters) of nutrient solution (divide by 250 for per-gallon mix rates).

- Adding 18 grams (or 0.072g/gal) of Agsil 16h adds 5ppm of Si and 5ppm of K.
- During late flower, add up to 150 grams (or 0.6g/gal) to boost K to 293ppm and S to 112ppm

Tip: For both of these formulas with coco, potassium nitrate can be swapped for calcium nitrate 1:1, in order to gracefully boost Ca and reduce K without changing N. No more than about 50g should be swapped.
Tip: For both of these formulas with coco, potassium nitrate can be swapped for potassium sulfate 1:1, in order to reduce N and increase S.
Tip: No boosters or modifications are needed until late flower, when potassium sulfate can be added (50-150g). Because of the high levels of P we achieved by using polyphosphates and shifting the sulfur ppms into phosphorus, we do not need to use bloom boosters. Bloom boosters use high levels of orthophosphate which could risk calcium depletion. Bloom formulas contain high levels of orthophosphate and usually do not contain calcium.
