I didn't say you didn't need P & K. I myself add HESI PK 13/14 as a standard feed to all my pots. as they're flowering and giving fruit I also increase the N supply.Agreed, some N is always needed and ferts should always be somewhat balanced. I stand by my opinion (based on everything i've seen) that P and K should be in higher proportion in the late stages of the season for flowering and fruiting. I am using roughly 1-3-2 now on my bigger plants, but in moderation, we'll see how they do.
