Thanks for the quick responses guys/gals. I feel better knowing that veteran growers, such as yourselves, don't see major problems yet.

The low pH I must correct. Like I said I only have hydrated lime. Should I flush them with water about 7.2 or 7.3 or is that too high?

One thing that concerns me about watering now is that the soil is still damp. I have very good drainage, the plants just aren't drinking much. I don't want to overwater and run the risk of root rot.

In an attempt to kill fungus gnats, I covered the top of the soil with perlite and vermiculite. After that is when the plants seemed to quit drinking. Could the vermiculite be trapping the moisture, keeping the soil from breathing? Should I scoop it off?

Yeah, I know. I'm the new guy with a million questions
