Haha was wondering about ray for a minute.
that is some oddball lime green leafing, did you figure out why the verigation?
nice clean set up bro...
That's is weird about the lite green leafs. What strain is it? How is ur ph? How old is the plant? What's the ppm? Are there any other leaves tryna turn? Dude I can only think of one thing that they aren't eating enough. Plants will draw nutes from lower fan leaves to make up for lack of nutrients if they aren't being fed well.
