First time grower and first time poster. I know I've seen this symptom in the various posts befor, but I can't seem to locate it.
Indoor grow, under two 400 watt mh. 24/7.
soil: Organicare Pure Earth. in 5 gal containers.
White Widow aproximately 7 weeks into veg.
Temps are low, as the grow room is an outdoor shed, lows are aprox 45 deg highs around 70.
Ph unknown as I havent got my meter yet ( Its on order)
Fed twice with Humbolt nutriants 5-9-4 at 1/2 streangth. and twice with Alaska fish
transplanted from 2 gal aprox two weeks ago.

The Large fan leaves on the bottom are the predominant site of the problem. New growth looks ok. The stems of the leaves that show the problem have a definate purple tinge to them. The younger stems look ok.

I have 7 PPP that look fine, and 5 white widow with only one showing advanced signs. Several other of the white widow also starting to show identicle symptoms.

Any help would be appreciated, see photos.
