Robertsanswered grow question 2 years ago Well you are growing in coco. I am a experienced coco grower. Your issue could be 1 of 2 things. Ph is one. If run off ph is not 5.8 that will do it. 2nd is if light is on at 100 percent ant 20 inches it is too bright.
Coco needs to always stay wet, plus cal mag will be needed. Your tds at 250 is likely low if that is accurate. Is all I see. Can feel free to dm me if you need more tips or help.👍
