We have a few plants indoor & the new growth is coming out yellow, were using GH Flora Series for the nutes & they are in Coco mixed with Perlite under T8 lights. Can anyone pleasee help me out with these girls!?
Like jay719 says, check the pH. I'd increase the nutes a bit. I use GH products- currently flora-duo and like them. Keep us posted, and good luck.
Real fresh new growth comes out a bit pale on quick growing healthy plant, tomorrow it'll be green and new growth will look pale, take another pic tomorrow and compare then act if need be
