reddish purple leaf edges

[spacemyface]

I'm growing some bag seed so i don't know if this is a diff strain showing its colors or if it needs somithing? The leaf edges are purple. Seems to start at the top of the plant, or thats where its most pronounced.
Thanks all

looks under nourished, have you been feeding it?

Bad nitrogen deficiency, feed it with a complete veg fert

Wow, I've been giving them 2tsp per gal.of grow big every other watering, which is about every 3-4 days. The others aren't like this one. Its not ph cause i've been keeping a close eye on that. This 1 is just a hungry biatch.

Hey all, quick question. So I fed them last night they seem about the same?? Not much greener. I believe FoxFarm recommends feeding everyother watering for soil. Can I feed my plants everywatering till they seem to look better. Or am i lookin for trouble going that route?
Thanks!
