Clawing

Hi y'all,
Long time grower, first time problem.
On the second resoviour for this grow I got it a little hot. Got some clawing!
Never faced this prior. No tip burn, just clawing.
.
Damage done, now I am at 1.6 EC and 5.9 to 6.1 fluxuatiton.
Has any faced this, if so what can I expect.
I flipped them on 7/4.
This morning.

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.
