One of my plants (Frank’s Gift is the strain) has been doing extremely well until recently, when a LOT of leaves have begun turning yellow. It’s definitely flowering nicely, and is way ahead of my other plants with flower size, and I know leaves will turn yellow in the latter stages of flowering, but this seems to be too much, and too early. I’ve just started giving it higher nitrogen fertilizer, thinking this could be the cause, but no effect yet.
Any ideas? It looks bad and I really don’t want to lose this plant!
