My curl is more like a canoe curl...but it affectin the leaves closer to the light. The top leaves are about 1 foot from the light (I'm maxed out hieght wise). Temps in the cab at around 82 degrees.
I've got a NL about 1 week into flower. The the top leaves are curling under a bit but there is no yellowing. I thought I read that this is normal in flower due to nitrogen being consumed. Is this correct?
I didn't have my normal camera..but this should give an idea. I just came out of 12 hours dark. It looks worse when the lights are on for 12. The pics have a bit of yellowing unfortunately
