Some of my plants are dying off very fast. The biggest and strongest plants are fine one day and dead the next. The grow room has been very hot. 90 day 82 night. Could that be doing it? The room has been hot like that before and nothing like this happened.

One new thing I did was to add hydrogyn peroxide food grade to the hydro solution at the specified amounts.

If everything is the same except for the H2O2, then that must be it.
Drain the tank, flush the plants and drain the tank again, re-fill then go back to the way it was before.

thanks ranger

I have on of the drip systems that has a resevior in the bottom of the pots. I used perlite on the bottom this time instead of rock and I think that it may have clogged the drain on some of the pots and made them drain slower or not at all. This may have compounded the problem
