Hey Stuggz, you get a PH meter yet? I don't have one myself. I haven't had a real need for it yet. But like P7 said, ditch the MG if you can. That stuff sucks. I used it on my first ever grow, and the plants grew for squat. I am using Fox Farm Ocean Forest now, and it's the bomb. Granted, it's a bit expensive, but worth every penny I think. Make sure you are not putting any nutes in there right now, because MG has time released nutes, at least most MG does, and it will harm your plants. Too much of a good thing is bad lol. Make sure your lights are 1 to 2 inches away from the tops of the plants, IF they are cfl's. And using a mixed spectrum of 6500K and 2700K is good. For veg stage, use more 6500's than 2700, by double. LIke 4 65, and 2 27. Somethign along those lines. You don't want the lights too far away because then your plants will stretch to the light, and it won't be good. I learned that the hard way my first ever grow. I can show u pics of it sometime if u want, they were all spindly lol.
Anyway, I have been learning alot, so if you have any questions, keep posting them, and I know evreyone here at RIU will be happy to assist!
