Yellow during flower cycle is tricky to deal with. Most of the time you compare the leaves around the one in question. If the others leaveā??s are fine and the plant looks fine then there is no problem. The plant will use up some leaves and they will turn yellow. Just pick them off and don't worry it natural.

At that stage you really judge the plant as a whole and not by individual leaves just watch new growth and see how they look. I don't mean to wait to long to act if there is a problem just don't over react.
Zandor Reviewed by Zandor on . early sexin.. Ok well I have a 3 part system. One half of my closet is clones and the other half is mothers. I have a 8000 lumen new wave t5 for 2 mothers and a 4000 lumen for the clones. The my other closet is the flowering room wich runs a 400watt hps. Anyways. I was growing my mother Grand daddy Purple and it was in the early stages so i had cool light on it with the little t5 wich is 4000 lumens. It got too big for the light and it started devouring all the space in the closet trying to suck Rating: 5
