Autopots WK8 Flower, Curled Leaves, Possibility NOT Heat Stress - What I’m I?

Hello all and thanks for taking a look.

Details: started seeing what I thought might be heat stress in a few of the plants; not all. Very slow leaf curl that doesn’t get better when cool, but rather is very slowly curling.

I was low on fed at the beginning of flower because I was using the same ppm for new 2.2G pots vs filling the 6.6G pots half way to around 3-4G of coco.

Temps in the 80-85 range
HLG 350R - PPFD lowered from 700-800 to 500-600
Fed is Jacks at 1000 ppm @ 6-6.1pH in coco with bennies and fulvic

I’m close to chop, but like to learn and become a better grower.

Thanks and have a great week!

What's the RH? Is there a fan blowing directly on those leaves? Taco leaves are usually caused by a transpiration problem..

Thanks for looking.

Good air movement: exhaust and in room fans.

Crazy thing is the other plants are looking good. It’s very slow moving problem.

Have you checked for bugs? Could be broad or russet mites.. They will taco leaves..

Yip. Yip. Looped them, but will get the usb micro on it in the morning.

Autopots are quirky. Might be my fed is off or they’ve been in the autopots for a few months and have odd root/leaf issues towards the end of flower.

I might run two clones next to each other next round, one in an autopot and the other in a 3G pot and hand water it.

USB micro was clear: no bugs

Still a mystery. I’m defaulting to salt build up in the coco, but it just doesn’t look like my normal over feeding symptoms.

I am bringing my ppm down some to see if that makes any difference.

Happy Thanksgiving week all!

Not sure whats goin on but I'm glad your search came up empty..
