I was wondering about that but am still too inexperienced to be able to discern. If it's PH I'd bet it's too basic. For the first week and a half ALL of the plants were watered with tap water. I ran a PH test my tap water the other day and it said the chlorine range was in the ideal range for swimming pools, though I did at least have the sense to leave water sitting out for 24 hours before using it. Geez! The water had a PH that was so high that it was almost off the scale for my particular kit (about 8.0). The MG soil is known to have a lower PH but I think the water sure drove it up.

I'm not feeding them nutes aside from whats in the soil but I think I might add some vinegar to my distilled water to try and lower the soil PH some more. Right now the water I'm using is between 6.5-6.8 which would normally be pretty close to perfect, I think. I do think that most of them are doing very well considering that they were tortured with tap water for abit. Fortunately for them, I do have some grow experience or else maybe they'd be much worse off.

Thanks for your reply!
