let me supply some additional information while im at it to make sure i am on the right track...
so my procedure so far has been i fill up about 80 gallons of my RO water in my 100 gallon reservoir. i mix my nutes including
hydroguard now and fill my under current system (seems to take between 70-80 gallons to get desired water levels). ive then been filling the reservoir with about another 40 gallons of ro water and mix in my additives (no base nutes) and ph the water and attach it to my epicenter through the float valve to maintain water level.
my system is running at 67-69 degrees via a chiller...my reservoir is not chilled, is this problematic?
my mixing reservior is clean and my epicenter is pretty clean...in my 6 connected buckets (plant sites) yes there was shit growing on the incoming air tubes. i attached a pic of the brown shit i noticed yesterday when doing my change out.
as far as ph burn goes...what i do is fill up a gallon of water from my epicenter and drop 2.5ml of ph down (advanced ph down) into that gallon of water. i then dump it into the epicenter and let it circulate to all the plants. i could try using less ph down, maybe 1ml per gallon and do it 2.5 times if you think its ph burn.
overall, do you see any issues with that i just mentioned? should i try incorporating some
great white? sorry for the long read i just dont want to lose these babies!
thank you.
