I was just about to ask a similar question. I've also noticed that some of
my finer-leaved plants have been covered by some brownish stuff which I
thought was some kind of algae. When I tried to clean the plants, I
realized the brown stuff washes off easily and makes the surrounding water
show a little brown tinge. The tank water (near its second week of initial
cycling) otherwise appears to be clean. The substrate I used is a type of
river gravel. When I cleaned it before I put it into the tank, I did
notice some dirt and other small debris but nothing serious. What I think
is that the two driftwood in my tank may have something to do with it. 
They made my tank very brown initially before the carbon in my Fluval
started to work. Do you have peat or driftwood in your tank?
