Gelato auto

[Airbone]

One of my auto flowers is struggling pretty bad.
It was very droopy, I figured overwater.
I let everything completely dry and watered very sparingly. Made sure it was dry and watered again last night.

Still super sad looking and has some rust colored spots on a couple large fan leaves. Outer edges of new growth seem curled downward.

Any info appreciated.

I'm sure you use Cal Mag, so all I can think of is PH off somewhere causing a lock out problem. Nute burn is a possibility, but it usually goes for the tips first, and the saw edge tips of the leaf. I'm sure you checked for pests, and they dont usually cause leaf curl. I always keep some pyganic around....if it is the beginnings of spider mites get busy, but doesnt look like typical white spots...bud looks good and healthy.

On the second pick I see a few fried saw edge tips, I'll go with a little nute burn.

Over feeding.

I call that turn and burn. I look for it on all my grows. A little turn and burn mean they are getting enough food.
