Your temp sounds good. The ppm can get ya and your ph. Maybe it will get here in time. Your ph you can check with swimming pools supply or fish tank supply they are cheap kits. Oh what kind of water are you using ? I use distilled that I make my self and I read that not only is the ph very low that important minerals are missing and not in good amounts in the plant food. I use dyna gro and the calcium and magnesium are very low in the grow and bloom formulas. I hope this helps. Mine are getting a touch more curl today. Come on cal-mag.
LOC NAR1958 Reviewed by LOC NAR1958 on . Just another newbie needing help Hi, I have recently set-up a grow room. I have 10 plants that are 5 weeks old and 3 that are 4 days old. I am growing some plants in a homemade bubbler and the rest in a drip system. I am using Dyna-Gro Liquid grow plant food 7-9-5 for vegetative growth. Also 3 weeks into growth I overfed and burned some of the plants but they have recovered well. Now, I am having some of the leaves curl up. Looks really weird, not sure if its a deficiency, overfed, too much heat.. not sure. The Rating: 5
