Lat night I switched my res to bloom nutes. I used 4 gallons of RO water. 45ml of A, 45 ml of b.. 15ml of muti-tool and 6ml of explode. In that order.. Ec was 1.8.. Ph was 2.7!! I'm not a fan of ph up/down at all.. It raises the ec by a good amount when its this far off.. I'm thankful for the res.. Because I could not handle adjust the ph multiple times a week. I've never used a nute line with such s low starting ph. Im going to start checking the rest as well just to make sure the ph isn't rising on its own too much..
