7.0-7.5 is too high for pot. 6.5 or so is about right for soil, and a little lower than that for hydro. Once you get up into the 7's nutrients aren't as readily available for the plant, which can cause fert buildups in the soil even though your plants are saying they're hungry.

If you haven't been using other ferts, than I would suggest looking into the whole fox farm line. 1 quart bottle of grow big and 1 quart bottle of big bloom should last you all the way through this grow and maybe a couple others if you don't have a lot of plants. They have an easy to follow chart that shows you what to feed and when. My plants have loved it, nice dark ass green leaves, overall pretty happy.

Also, this is a helpful link for diagnosing plant problems. Its called the plant abuse chart and has pics of leaves with deficiencies so you can compare how your plant looks and also tells you what to do to fix them. Not as complete as the one in jorge's grow bible, but definitely a good resource.
