So I can tell the plants are doing much better, ph was fluctuating before it was high everytime I checked which makes me believe I probably did have something going on in the res. But now the ph is stable with my once a day checks. Water temps back to normal at 74. Reservoirs have overall better or more neutral smell. I cancelled my peroxide order after some more thinking and talking with others on here.
I believe that the plants were stressing because of the water temps, which were high because of ambient temps.
I have lowered the lights on temp to below 80. I am also using water from the dehumidifier to top off instead of tap.
If it's not broke, don't fix it? Lol
The one plant that seems 2 weeks ahead of the others is getting some frost

And the last plant is finally showing it's lady parts, all is well. Plus I was able to order a 150w quantum LED for $25 on Amazon today with a coupon. That will be for the next grow with a total of 8 plants.
