Looks good if it is like GH drops. I wouldn’t go any lower but that is pretty much the color I like unless growing in peat.
Spring for some cash, like $20, and get yourself a PH pen tester, The drops are ok for fish tanks, but that's about it.Welcome to DUD's random question of the day.
I've lost the little bottle from my PH test kit <insert cliche stoner comment>. How accurate do I need to be in replacing it? Is roughly 10ml close enough for an accurate measurement?
Cheers gurus,
