Ok, problems in paradise. Yesterday was day 3 of my plants in a fresh res. I checked the roots (white healthy and growing nice), adjusted pH (form 6 to 5,5) and added some freshly brewed tea. Today I check pH and find it at 4.3. I find pieces of white snot floating in the res, and roots are geting white to brownish slime on them.
I was brewing 2L of tea with 20 mL ewc, 6,5 g od fructose sugar and half a scoop of great white. It was bubling with a 3W bubler for 48 hours. Thing that made me thinking now is that I got no foam and no biofilm in my brew. Could it be that my temps were too low (19C - 66F) and nothing grew on the sugar, so when I put the tea in my res I only introduced food for the nasties?
My res conditions should be OK, it's a dark green thick plastic bucket covered in black plastic sheet with an improvised styrofoam lid again covered in black plastic covering all around the plants so no light comes through the net pots. Teps are at 65 to 68 F. Air is provided by a 18W air pump pumping through 4 airstones. I'm using Advanced hydroponics dutch formula nutes at about 0,5 EC.
I've washed the roots as best I could with a sprinkler and pure water, let them sit in a fresh res with some H2O2, then after 3 hours put them in a clean bucket with RO water and a scoop of great white.
Any sugestions on what I might be doing wrong?
