lighburn or overfeeding?

[temple_of]

Pls advise, is it light burn or overfeeding?
2-3 days ago it started, I reduced the lights and moved them up.. the leaves are starting to curl up on top edges.. I believe it is light burn or heat stres.. dont believe it is overfeeding as I use biobizz and an carboload.. hm.. plants are in day 50

I believe curled up tips is heat stress and curled down tips are over feeding.

May want to lower temps in tent or raise your lights. But I'm a newbie so I'm sure someone else will be much more helpful than me.

Just my two cents on first glance. Hope everything works out.

It looks to me the same.. I am using led, bud I added 3 days ago few cfl to improve it, but that happened, so I moved them away and moved led higher.. hopefully it is not so critical

Actually, the pictures are not the greatest, but it looked like you may be dealing with both to me. Some of the pics show a clawed down, burnt edged leaf, and other pic shows the alligatoring and frying of heat/light stress. Have you checked your medium pH, and have you been pHing your feeds?

... yeah, pics are too bright, reshoot some please.... I'm with HM, might be some of both,.. how far away were the LEDs and CFL's? The lower leaves are not light burned, looks like P defc. maybe,...
