Ok, I started to notice this last night and tonight its even worse. There is a good amount of gsa on the glass, as well as on some of the leaves and wood. I also think that gw may be developing. Previously, I was running 4x54w for ~12 hrs and 4-5 hrs of that was all 6x54w. Today, I just ran the 4x54w for 12 hrs ONLY. I guess I should back off of the lighting until the plants grow in more? I have some plants in my 20g that were leftovers, but I can move them over (some Moneywort, mayaca and hydrocotyle). I know the water flow is sufficient, although Co2 is a BIG guessing game right now. Currently, I have it running around 4-5 bubbles/sec. Since the aquasoil affects the ph, I can't even get a ballpark reading, so plants (and algae) are the only indicators. My guess is Co2 is too low.
How should I fix it? Simply turn up the needle valve? Or, consider an alternate way of injecting it? Or something else?
Here's a few pictures. Maybe this will help give you a better idea of what I'm looking at here:

Similar to previous, but take a look at the algae-covered wood:
Hairgrass & HC seem to be doing ok. I'm sure if I ignored this for another day or two, that might change. Hairgrass is spreading a bit, but HC has yet to do so (but its not doing poorly either):
This is what I've been dosing:
I dosed about 30-35 mL of CSB+B solution a few days ago. I was told that with AS, you don't need to dose. I'm not sure if my situation is different since lighting is fairly high, or if Co2 is still the culprit.
What say you??
Up the Co2 and keep everything else the same? Or something else?
