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.

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
 
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.
