Dirt or hydro?
How old are they?
using Ferts? How often?
Could be over fertin' and burnin' 'em too.
Yeah, you need some airflow even when the lights are off.

It'll kill them too, in a closet.

Re: there all dieing

If the ionizer is off you should be okay.
Ionizer will damage plants if they are to close to the plants.

Work on the ventalation, gots to have air flow.
2-3 area changes an hour is best
In other words,
if you have a 6 cubic foot area you want to move 12-18 cubic feet per hr.
