Leaf canoeing

Hello everyone first grow in a few years and I'm running into some problems. Plants are 23 days old zkittlez glue. I'm growing in a mixture perlite coco Canna and Happy Frog. I have 60 girls under 3 hlg 650s for now. Everything look good until about three or four days ago when the canoeing started happening. I fed them for the first time about a week ago General Hydroponics micro and a calmag supplement. Light was at 30 in and 100% I've turned it down to 50% and raised it to 33 in

Should be ok now that you dimmed and raised the lights.

Sounds like you got it my friend. No worries.

yeah looking way better. They also needed a little bit of a drink but it looks sweet in there now
