the purpleish is from the plants not growing like they should. the longer the stalks "sit there" without much growth, the more purple it gets, (same for older plants) after purple comes brown, not bad brown , just the brown u see on the
bottom of stalks on older plants. how tall are they now? i know ice gets very tall if not tied down.
here is a pic of ice that is just starting the "shit"

Nirvava's Ice
that shit is junk. smokes pretty good but , no 2 seeds produced the same quanity, quality, or color. so it is just unstable. I have 5 strains and they are all havin the same probs EXCEPT Ice. it has problems of its own. the reason i am so dead set on ice being junk is because i gave a few clones to my buddy and he is havin problems with it too, and this guy never has probs.
I can get the ice to do VERY good for the first weeks of veg but if i keep vegging it dies (well not all the way dead because i dont let nothing die)
it does seem to perk up in flower (unlike the other strains) but
only if i flower them right away (about 8-10")
my mothers of ice are forming flowers in 24/0, and i dont mean "low light cylacts" i mean strait formin buds, trichs an all.
i have tried everything BUT doubleing or tripling the nute mix, hell it might be a real heavy feeder?
i am not knockin the shit (yes i am) but with my buddy havin the same prob as me , i would say its the strain.
