Serated edges of leaves turning upwards

Hope this helps:
I run Samsung QBs (set to the maximum setting of 240 Watts). 18 inches is the sweet spot for me.
Any lower, most of my strains will show curled leaf edges (like yours) at the top of the plant. This level of 'stress' can stunt growth (so I have been told)

from the tops, it was 16" (or below) that caused leaf curl. 18" (and above) stopped leaf curl for me. Yes, they recovered (I believe it needs prolonged exposure to intense led light for major issues). imo - your plants problem was small, and you raised the light, so you'll be fine :)

Thanks for Ur help mate
 
A little wild ... look into training techniques / minor pruning / leaf tucking etc. . Not only controlling potential bud sites , BUT also air exchange and transpiration.
It looks pretty good overall btw.
 
These help diagnose threads with pics are hard by nature ...... I don't see actual "tacoing" on the leaves and other lady shows nothing on the tops. Doesn't mean it can't be environmental, just guessing on the internetzzz without a physical presence.

Raising the lights should be a easy check though. Can tar and feather me later riu, much love

Good luck grower

That's not genetics. It's not a major problem, plant's can grow like that without major damage, but it is environmental without a doubt

Super crop it or raise your light, up to you.

Yeah agreed have raised light thanks for advice
 
Could be a bit of salt stress too looking at them again. That'll exacerbate any issues with heat. What's the EC of your base feed?
 
Only fed once with bio bloom and bio top max half measure wen flowering started about a week ago
