I would say you may be adding nutes to soon for your girls, bought soil has all they need for their first month or more. The white stains could be a bit of a ph fluctuation. In your soil. Cheers

Friends need your help! pH 6.2 EC 0.7 Please help me understand what is the matter because of what dry tips? At first I thought it was all because of the light! but the light raised high and reduced power to a minimum! then I thought that the fan was too strong but I put it so that it would blow into the wall

Before it becomes a real problem Day 39. I realized that I was blasting plants with too much light as of the last few days. Made the switch to bloom nutes. Any ideas what's going on here. I want to fix this before it becomes a real problem.

Never really noticed this before, but it's also been a long time since I've grown inside. The tips of each jagged leaf edge is pointing up. Just curious about it.

Starting-to-Cook Deficiency?I can’t seem to find issue. Look close at brown leaf spots. Rock solid variables with a tweak in the diet in week 7. Was the light cooking the life out of the canopy for last two weeks? Light was 8” and 1500-2000 PPFD before I yanked the top shelf out 3 days ago for distance.

Leaves light-green? Give more nutrients?What do you guys think of the leaves on this plant? She's about 2.5 weeks old in DWC. The newer leaves are looking a little light green in color, especially when compared to my GSC. Should I provide more nutes? You can compare the lighter leaves to the darker set lower on her.
