Brown spots on leaf, Fungas Gnats?

[IceR]

That's a rough idea of what PPM to feed a particular sized plant

And when you check the runoff you want it to read somewhere around the strength that you're feeding it at, plus or minus 100 PPM or so, and you want your pH between 6.0 and 7.0

Thanks for all the help Beachwalker, will post results :-)
