What kind of soil are you using. I use RO and I don't check run off or bother adjusting the PH of my nutes. I established my soil before planting and have'nt looked back.
yeah the biobizz allmix is new to me too. seems like its got alot of feed in it as the plants im currently growing have a small amount of nute burn, so im watering them really carefully, prob wont even start to feed during the veg stage
i use biobizz allmix and it has got alot of nutes init best thing to do is just use water for the first few weeks and then start to add nutes when your plants show they need it
When I did check the run off from just my soil it showed pretty low PH. I did'nt add nutes until transplant. I put my seedling directly into the RO soil and did'nt see any burn. Once the roots were established and she was in her last home she took off. I hit her with quarter nutes. I had a little problem with Mag def, so I hit her with some epsom salts and that cleared up in about three days. The flowering pictures she'd been budding about two and a half weeks. I wanted to bump my CO2 levels, but I could'nt justify a big CO2 set up for this relatively small grow, so I'm using dry ice. I've read that ywo pounds of DI will elevate CO2 in a 10x10 ft room to about 2000 ppm for 24 hrs. I have it in a small styrofoam cooler covered to regulate the CO2 and slow melting. I'll let you know how it turns out.
