Yellow and brown spotted leaves?

Alright stoners and stonerettes, here's the problem. Theres these plants in a small cabinet grow box, Purple Haze x White Widow clones, and they have began to develop yellow/pale leaves and brown spots, some leaves are becoming crunchy, and dead.

An opinion of one of my colleagues suggest that this may be the result of the cabinet being too hot, due to a recent heat wave.

Can anyone help me diagnose and fix my delicious babies?

Were it ambient temps causing this the entire plant would show stress. Looks like it's limited to near the base. Is that correct?

Your best bet is to start a thread in the Plant Problems forum, copy-n-paste then fill-out the troubleshooting form. (the link to the form is in my signature)

Are you spraying or splashing them with anything?

If I were you I would get rid of those plants, they look infected. If you have any other plants in the room that dont look like that, get the infected ones out ASAP so infection doesnt get to the healthy ones. Good luck. :(

lol clasic leaf fungus, should have neemed them great pics though, they need to be in a arcive or sumthin, leafe fungus sucks, but usuing neem as a preventative keeps it away along with powdery milderw, and afids, and just about anything, this is why I always rcomend preventative spraying

in the futer people runing into these rpoblems, pull off the infected leaves, spray with fungicide, or neem at this point neem is not gonna totaly kill the fungus but if you pull of the infected and continute to neem the plant and the garden should be ok, however if left like this leaves can fall to the soil and then you have soil fungus and fungus bugs.

to avoid use neem oil once a week or every 3 days, as a preventative so this does not happen
