hi guys,

im on the 4th week of my second grow... got 6 females out of 10 so im pretty stoked! the plants are doing alright however they are starting to get yellow not so healthy leaves at the bottom.... i know you are supposed to give the plants more Nitrogen during vegetative growth but when is it time to start cutting that down? because i started giving the plants a supplement of P + K (P-8 K-4) 2 weeks into the flowering and thats when the leaves started to get yellow so a couple days ago i gave them a bit more of the fertilizer (N-7 P-3 K-5)- that i gave them during the vegetative cycle since as far as i can tell its lack of nitrogen which is causing this. Im not sure if that did the trick but Id like to know when to stop giving them N and concentrating on the P + K or do I need to give them N the wole time? btw, this happened during my first grow also - leaves turning yellow and falling off, i want to try to avoid this here.

thanks for your help!!!
