well, I got a digital ph meter. It reads 3.68 , which, according to everything I've read is pretty much on target. I've gone back to suspecting nutrient levels etc. I don't have the fancy brand name crap y'all got, I got the generic LDcarlson stuff. It doesn't make much sense though, I have "nutrient" and "energizer" but both seem to have the same ingredients in unknown quantities. One has urea and dap, the other has dap,yeast hulls, mag sulph, and B complex.
Everyone talks about balance... How can I balance it if I use "proper" doses of each? I don't know. I have probably already ruined it when I added a multivitamin pill! Anyway, I just eyeballed a little from each bottle and repitched EC1118.
BTW, the airlock has been steadily bubbling the last few weeks, but maybe only 1 bubble every minute or two, must just be degassing?
SG is still only 1.070...
