It sounds like your plants have stopped growing because they are
CO2-limited. You can easily (and cheaply) add CO2 by using the sugar-yeast
method, described in the Krib and in many APD postings.
The transparent leaves may be due to a potassium deficiency. I suggest
using PMDD--this will end the yellow leaf problem, and will cure your hair
algae problem as well. The PMDD paper and recipie is also contained in the
Krib, under "Fertilizers".
