Is my LSD 25 auto wind burn or just a bad go at it?
Help please. My LSD auto is flowering but she looks so sickly. She did fall and lay over after germinating for a few hours but she bounced back. I'm not sure if it's heat stress or if it's from the wind. The grow room is 75 F two fans. Ac running on dry mode. Mars hydro ts 600 at

Leaves started hanging down all of a sudden
Leaves started drooping/curling down quite a bit all of a sudden any idea why? Haven't watered since the curling down started as I guessed over watered but it does not seem to make a difference. Some of the leaves are now pointing straight down hard to get a good picture of those

Light green leaves in color and burnt tips. Some leaves have brown spots.
Hi guys, can you please help me diagnose the issue. The plants are in BioBizz All-Mix soil. Treated with Bio Grow, Bio Bloom and Top Max from BioBizz. Also BioBizz Cal-Mag in the past week and 1ml of B52 (twice). A week ago I flushed and initially they were looking good.

Soil too rich for my youngsters.??
Soil too rich for my youngsters, causing their leaf tips to point down. Being auto's planted them straight into their final pots and the soil I choose was biobizz all-mix. I'm now wondering has this been to strong for them. Has anyone experienced this and what outcome to expect.

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Leaves suddenly droopy and curled at the tips, although look a healthy green. Doing DWC. Help please!
They look overwatered, but this is DWC and I'm not top-feeding. Not sure what is going on as the leaves, themselves, look a healthy color. Pics from 3/25 show this, and I have detailed info in my diary. I have tried dropping humidity down (was keeping up for VPD). Thanks
