drop your ppm under 1000 and add h202. Keep your res temps below 70 to be safe.

BTW slime is a huge sign of pythium(root rot).
They didn't feel/look very slimey. Maybe a bit though yes. The bad parts. Darn - What a shame. I'll check the temps now. I'll remove the new nute solution to take the ppm down a bit.

Snoop - I have 3% H2O2 on hand. Each bucket holds about 3 gallons. Do you have a suggestion of how much to use per gallon?
