I just read your thread at grass city and that watering advise is no good, if I may be so bold to say:

I always add water plentiful as to get lots of runoff and be sure let it dry out for a couple three days or so. I check PH in, PH out and adjust accordingly. If you only add a half cup every time you'll get no runoff and build up of salts. This pretty much goes with my first post too. When they say let them dry out between waterings they don't literally mean totally bone dry. "They" tend to over exaggerate, especially if you live in a dry climate. "They" also tell you to under nute as you may start lightly after first set of real leaves. IMHO, YMMV
