You should have about 40 PAR at the substrate. That is enough to let you grow almost all low to medium light plants, so your list of plants should be OK. I'm guessing your KH is not in degrees of KH, and is about 2 dKH, which is consistent with soft water, as is your GH, if it is degrees of GH. The high pH is puzzling, but it could be that high and still be normal.
