Hello all, i have a general question about the water i am using. I get water from the corner stores purified water station that says it filters the water through RO. When i ph and test its ppm's i get a ph of 5.6-6 and 20-23ppm. Granted that i raise the ph a bit, would i also need to add cal/mag to my water to feed 8 day old seedlings planted in Fox Farms Happy Frog soil? EDIT: MY tap water is useless so that's out of the question.
Also, i purchased a bottle of SUPERTHRIVE; when and how should i feed this to the ladies? When do i start using Nutes @ 1/2 or 1/4 strengh? Using Advanced Nutrients, fox farm happy frog, have CALiMAGic, ARMOR SI and SUPERTHRIVE. Strain is GREEN CRACK X CORE.
