Sick plants need help

A question from a fellow grower:

I now have 11 plants 4 northern lights auto fems and the rest regulars. I think they are sick.
Can you tell me what I need to do please. Temp is at 80° f. Right now 250 watt hps on 18/6 light cycle.

Heat stress what are your temps like and humidity what kind of soil are you using?

A quick question is that miracle grow soil ??? if so you mite want to change it out … and yeah the plant looks like it dried out from a hot light . H

Suggest re-poting and take a look at your fans use and plant’s distance from lighting
