What the fold ?

Hi there everyone !

First time grower in DWC . So far so good ,everything looks fine except for one plant ( out of 4 ) where the leaves fold . It's not light burn ,my 600 watts is at 20 inches from the tops and the temperature is arourd 75 F.
Humidity is around 65% lights on ,an 90 % lights off . I have air intake and outake fans plus two oscillating fans on 24/7 when flowering . Total ppm is at 1200 , it's too high because it's strating to show on the tips .
PH is at 5.8 . ArmorSi ,CaliMagic,Hydroguard ,and General hydroponics flora series .
The plants are at day 23 flowering .
Can anyone tel me if this a syntom of missing something or too much ? From the charts I've seen ,a lot of them ,I never saw that kind of fold . Is this just genetic ?

prolly not missing something...using a complete system

you've diagnosed it yourself below, some plants love those salts, some not so much, lower that one maybe?

You have too much nitrogen. What ever is supplying that cut it back. It would help to have a pic in blue or natural light. The N tox is obvious from the claw. Its hard to tell what else is going on in a hps pic.

That really don't look bad. Just back off the N a little and you should be fine. I don't see any bad clawing in that pic.
