Looks like clawing leaves, nft table .. pic att

Hi guys,
Recently discovered there is such a thing as claw leaves, which apparently is an issue and needs addressing,
6 x tangi kush
6 x star dog
8 days into flower
2x 600w hps
E.c. .8
Well water .....Water temp can get low as 55f but mostly aroun 65
Canna flores a & b
Silcone
Cal/mag
I let them run on constant flow during lights on and every hour for 30mins when off
I had an issue with fox tailing so anxious to avoid this time round, feed schedule is at minimum to reduce N overloads, lights are 18" plus away.i flush for 24/48 every days or so to keep them clean and mean
Do i have a clawing leaves issue and if so what remedy can i apply to fix if any,
Starting growing again after 20yrs, didnt have this issues back then so any advice would be appreciated.
Tks Guys
