i just noticed that my stems are turning purple. i'm not sure if this is from the strain or if there's a problem. here's a few pictures...



i've also got another problem: the tips of the leaves are starting to die. this was happening before, but as soon as i transplanted the plants into bigger pots (2 liter bottles), the problem was solved. here's some pictures...



any help would be appreciated.
I would check your ph level asap, I had the same issues and my ph was high and I had nutrient lockout.
ok - i'll get a ph test kit asap and let everyone know the level.
