Thats nothing.. One of my plants are pretty ugly. but one looks great. They are in the same DWC so they shouldnt be much difference. Im guessing its the light. The green one has 2 CFL warms, The brown plant has 1 daylight CFL. any one know what it is?
maybe i can help abit hun,
it looks like a nute problem to me. you should check the faqs of rollitup, go to plant problems. once you go there, click on ph and nutrtion problems.
itll show you pictures of what the problem should look like.
youll find your solution there too.
you probally have to flush the plants.
by the way, your babies are in veg growth, warm lights promote short internodes and weak stems. you should try to avoid warm lights during this stage for a higher quality bud.
hope i could help.
