Ch33cHanswered grow question 4 years ago Hey if you look at my Dos si Dos you will see i had same issue with this. They start off pale before going full yellow.
I wasnt sure if i was to slow to get some cal/mag into her feed. I have done many Coco grows that havent asked for any calm/mag and i have had some that just get sick without. But as soon as i got this into her feed and raised the light a little she bounced back.
If not that it i would narrow it down to either lacking Nitro or maybe lights to close?
