Hi All...

Still pretty new to growing (2nd grow) and getting a little worried. I was doing some LST because of the low height on the tent but stopped to minimize stress factors.

Symptoms:
Spots, yellowing and twisting in middle of leaf since I switched over to flowering. Worried that it's nute burn but can't quite tell. It seems to be the worst near the edges of the light.

Thinking it could be wind, light or maybe humidity issues? The RH has been fluctuating a lot in the area but it's generally in the 60 range. Was in the 70s a few days ago and dropped to 55 at some points.

Not sure how to help them.

Strain - og kush and Blue Dream
Medium - coco
Light - sandalwood LED
Fertilizer- general hydroponics
Pot - 3 gal fabric pot

Any help is really appreciated

It doesn't look like nute burn. Possibly a potassium (K) problem. I would think lockout or some kind of interference, rather than the lack of the nutrient.

I can't tell you what to do. I have no experience with coco. Hopefully someone with coco experience will jump in here.

Thanks so much for input. I thought it could be a deficiency but hadn't considered lockout. I'll check out some causes and remedies for it to see if it's maybe something in my setup or watering.
