I've been using raw salts for a few months and these are my findings so far. Base water 40-80ppm Coco - DTW Beds - I've had really healthy results with the following (in ppm) All the way from Veg to Day 10 flower. N;P:K:S:MG:CA 159 48 192 74 53 100 That would be 3.3 : 1 : 4 Promix blend DTW pots- The same mix but they aren't as healthy. It seems they want Something more.. Not as vigorous, no obvious deficiencies. Questions - Does Peat/Promix usually need more P ? Or is too much K? Coco - I want to continue this amazing growth but am a little weary to change to a different formula. I was thinking lower the N, K and Ca a bit. I can do this with what I have: N;P:K:S:MG:CA 118 57 168 70 54 85 Thoughts and comments welcome!
