Power Plant's leaves dying off - not nute related

First pic looks like a P deficiency. 2nd pic temps look ok but I would hang that meter from the light so it sits at the top of your canopy for a better temp reading. Meter may stay cool because it is in front of the fan and below the canopy. And I hope that is not the only circulating fan and it doesn't look like it oscillates. I use my 600 with a sealed reflector and a 6 inch fan pulling out the exhaust and 2 oscillating fans and it still gets hot in there. Heat will make plants look sick and hungry so check that first and make sure you are getting lots of air flow.


And in pic 3 they look like they're wilting, possibly from high heat or low air flow considering you are running dwc and it can't be needing water.

I know some people hate to prune plants but when my tent is that crowded I prune to let in the air flow but I never prune beyond 2 weeks into flower.

Hope this helps good luck.

Yeah, I do think I need more airflow..... I do have a oscillating fan not pictured here, but I let these babies get to big before I started flowering them. This pic is at 3 weeks into flowering, so I'm hoping things dont get too much bigger or I'll be out of room....


I changed up with fresh nutes today and gave a nice foliar feeding.


Do you think it could be a lack of light causing the die off on the lower leaves? most of the plant (upper 3/4s) are doing great.

yes those leaves are dieing because of lack of light, i don't see any light penetrating down there only shadows.
