Has any faced this, if so what can I expect.
I flipped them on 7/4.

had this issue once growing hydro, roots looked funny, plant grew fine after tho, i fought it for a long time, did complete system flush, unsure what really fixed the plant, but the clawed leafs stayed the same the entire time, flower sugar leafs looked fine later

Looks like nitrogen toxicity (overfeeding) you should wash up the roots of your plants then reduce the amount of fertilizer.

Ye, like comment above. Clawing points specifically to excess Nitrogen
You also got some P deficiency going on. (bluish lower leaves + red stems + flowering phase)

The plants P uptake rises during the 1-3weeks of flower.
After that go for more K heavy.

As stated, looks like n tox. Affected leaves will stay that way, focus on new growth.

Thinking I have halted the Claw, but I am not seeing any pestils
.

Flushed the hell out of them, over the past few days I have flushed to with 12 gallons of pH'ed to 6.0, 1 gram Epsom and 2 ml per gallon of solution.

Method? Looks like dtw coco? If so looks like heat, whats the air temp? My pheno would also purp and twist just like this if light too intense. Whats the ppfd at canopy? Watts and brand light? Led?

I hear so often of claw means N tox. Idk about other methods but sure my pheno looks dark N tox locolized sometimes overall. Still dialing in a new setup a few runs in but this new pheno I tested clawed a lot around heavy lit areas no dark leafs. Correct if wrong but this why Im not quick to lean towards N tox.

Ive ran into bigger issues trying to correct little things like that. More of a frequency related thing but I tend to find a sweet spot in ec and stay there precisely. Then work on allowing some dryback vs overwater. Im studying if overwatering causing gutating is a lower risk if to keep it on the dry side.

Coco/Perlite, 3/1 ratio.
Air temps have been around 80⁰, light is at inches. Not sure of ppft, height is 25" above the canopy. Running lamp at 80%.
HLG Scorpion Diablo, 650 Watts, yes LED.

Those from what I know are really strong. Im not knowledgable on lights just ran my clones under a few different kinds and noticed differences. I would read that people burn their plants easily with them. Just that they are strong.

Like, I was using mars hydros then tried a vipar ks3000 but the vipar at 100% burned my clones. They looked similar to yours now given some visual signs overlap and could be something else. So 75% was the highest I pushed the vipar for.

I use 2.5x5’s got two which is like a 5x5. I use 600w max but usually around 450-550 range if its really hot and dry. If the plants look like they need a dimming. So 650w sounds great but ya. You would know if that is potentially why, heck Im sure youve grown much longer than me.

My veg plants or at least my main pheno of a couple years needs dim lighting for veg. Like, analog dial style with it all the way next to off position. Its 60-70F basement but moved a couple clones upstairs to 80F and still needs same lighting.

It did give it a boost tho, Im in a rodeo this run. They would look like yours in veg if I raise the intensity. Also in flower depending on the light but should be in the 75% range. Like from day one but I did 25% a day from day one flower this run. Extra smooth touch.
