ok, so i just tested my tap water (which I have been using on the plants), and it the pH is 7.3.

Im guessing my soil is also too alkaline, since I've been using that water all this time. Should I flush the plants now to fix the soil (the leaves have started curling a little)? Or should I wait till next watering and use, say, pH 6.0 water to balance it out?

First grow here, so help me out please!

THanks!
joe.
