I be findin that in my grows the big fan leaves start turnin yellow in the flower stage caus the plant be drawin all its energy and nutrience from areas of the plant to feed into budd production. I have never gotten my nickers in a not about it just seems to be what they do but then gain without pics i could be totaly wrong. Good Luck hope yu getter figured out pilgrem!

yeh, I'm use to losing the fan leaves early but.

I'm don't think this normal , there seems to be too many this early on ,I know a pic would help but all pics I have seen and believe me I have looked at all I can find on the net, and that si a hell of a lot and it looks like pure old nitrogen defiency, just wondered if I should give a dose of Grow Big with 3 to 4 weeks left
