caused

Ok so one sixth of my led panel is out.. they dont look burned out tho.. could it be a power supply maybe its like (10-15 LEDs x 10-15 LEDs) but like said they don't look brown or burnt.. what could it be?? It's a mars 700 also

Bottom leaves yellowing and dying could this be caused by fungus gnats

First time indoor. Poured to much water and gave the fertilizer presumably in the excess dosage two days ago what caused the stress shown in the image. Plant is deteriorating but still alive, what can be done could anyone advise some helpful action. Thank you!

Hey 420 Friends ! I read a few things about foxtailing as it is happening to me right now lol ( well not to me but to my ladies ) But it seems like some people say Foxtailing is caused by the genetics and some say its caused by to much heat ? So whats the Truth now lol ? Thanks in...
