well here is how I wind things mentally...
I follow all the rules of coco...
I broke the rule of median drying out...
So it made 4 or 5 tops go all silly..
But yet the one that was drooping the hardest
didnt do that, it just had some tip burn( which is what I would expect to see)
when drying out..
As for the lights intensity,
does it actually cause the plant to uptake more?
I dont think so..
I think that is regulated by heat, or VPD.
And They are vented so canopy temps under light or about the same as under led..
But it has to be from drying out! Some do it and some dont! I cant think of any other variables...
