*indoor 86-89F
*11000K LED lights 18/6, 2" over them (sometimes i give them 1-2h of direct sun and wind)
*water from the bottom every 2-3 days
*only the bigger ones got this symptoms at the same time, the younger plant on the tray are fine
*no fert'


maybe its time to transplant them ?

*the growth is very fast - this is from 8/11 (5 days ago)

I'd say they're ready for a transplant, but not necessarily that that's the problem. That first picture slightly reminds me of when I sunburned my Trinidad Scorpions without hardening them off, but none of the others really suggest that to me.

Most of them look fine but my uneducated guess would be some sort of fertilizer imbalance for the ones that are yellowing.

Any way i am going to transplat them tommoro
And they will stay outdoor

So will see if the new condition will get them right
