Depends on this and that. How big your pot is, how big your plant is, how many days in the pot, how many ml are you feeding, strain, what soil, ect
I use PBP and I feed at 10ml gallon in veg every time and it works nice, I also pot up several times so they fill the pots with roots fast and can handle it every time. If you pot up into a larger pot with hot soil dont feed as much.
Once there in flower Ill feed almost every time, again i feed weak at 10-15ml gallons with aditives like
calmag,
hydroplex, that add ppms to the fert. If you doint use these you could feed higher, but i think the recomended feeds by
botanicare are way to hi. Start low and if your plants need more you can bump it up. Also I use the PBP grow the first 2 weeks of flower or the plants will yellow on me, from my low feeding program, and the OG platninum i grow is a nitrogen hog. Hope that helps
