7 bags of R/O!? You must have a decent size grow! I only need like one bag, only ever vegging 4 at any given time. I guess since I am over loaded with seeds and have plenty more plants already vegging/cloning and germinating as we speak, I'll just try a lil bit of everything. My SS alone, my SS mixed with Pro-Mix, etc. I have a few Sativas that mean the world to me so I realllllly hope my SS is up to snuff. I'm almost positive I should be ok for the rest of this grow if I can just dial in my PH. I am learning a lot here by messing up. Dolomite Lime seems to be the number one thing to add to any soils to make sure the P.H stays leveled. Do you bother letting your water sit for 24 hours to burn the chlorine off? When my water FIRST comes out the tap, it's 8.6 but when I let it marinate for 36+ hours it drops to 7.6. What I am getting at is, I could feed my plants with 6.6 water using my current nute selection if I can feed it RIGHT out of the tap since it lowers it by 2.0, instead of allowing it to get to 7.7 and it lowering to 5.7 but if I have to wait to de-chlorinate then I'll go with your 1/4 servings instead to get the right PH. I promise I won't keep bothering you. I am just about to hop off the training wheels and start riding alone for awhile.
