Move your light to 22 inches above the canopy, you have a good case of light stress. Happy growing.

This particular plant might be in a hot-spot in your tent. If the lights are powerful and the airflow isn't adequate, there will be points in your grow area that retain heat. This could be the issue.

To much light!! Try 15-20% less light if your light is Dimmable otherwise put your light 10-20 cm higher

Rusty Leaves 3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.

So a bunch of my babies are getting this extreme leaf curling. It happened when the lights were off for only like 3 hours. Could it be windburn or Humidity? Nothing is out of whack in the Grow room temps were under 80 and humidity was >70 because I have a dehumidifier. Thanks

Weird Leaf Problem New leaves show strange twisting/curling. Humidity ~50%, temps 28-21°C (D-N). Did LST last week—could twisting be due to reorienting to light? Using All-Mix soil, Bio Grow, Calmag. Water left 24h, not pH'd. Some leaf holes caused by me. Flipping soon—help resolve this issue!

Looks like light stress I assume with the canoe and curl. Moved light from 100% to 75% Stil at 35in from canopy. Should that do the trick? Also should I have already had it at 75% and moved it to 100% during flower? Or how do you guys do your light power
