Newly planted tank not growing so well...

Hey all, I've kept several successful tanks on the PPS Pro method and have just started another for the first time in years. Problem is nothings really happening and I've got no idea where to turn, hopefully I can find the answer here.

Tand specs:

3 week old 75g moderately planted.
Pressurized co2 (bpm is very high, difficult to count)
ADA Aquasoil
Plants are barely growing, GDA is on the glass, starting to show on the substrate and some plants...and green strands of algae starting in spots. I was doing 50% w/c every other day, tank still seems slightly hazy.
8 hour light cycle (4 x 54w T5 HO)

Parameters as follows:
pH: 6.2
KH: 2
GH: 5
Nitrate: 30-35
Ammonia: 0
Phosphate: .5

PO4 seems low so I just added a touch before posting. Also since I've been noticing low PO4 levels I've doubled the amount that the macro recipe stipulates.

That seems to be about all I can think of at the moment, hopefully someone can see where my issue is.

Thanks,

ps only inhabitants at this time are about a dozen nerites.

Im suprised that your ammonia levels are so low, since you're tank isnt that old. This is a good thing though! My first suggestion would be to turn down the CO2 and lower the photoperiod by at least an hour, because that seems like massive overkill. How many and what kind of plants do you have? Sometimes, adding more plants helps the plants to outcompete the algae, and some plants are really slow growers, so you might just be helping your algae grow.

Thanks for the reply, I'll look into more plants perhaps as it's moderately planted I'd say. Here's a list of what I got for plants thus far:

Alternanthera
reineckii 'pink' roseafolia
Crinum calamistratum
Echinodorus 'reni'
Fissidens fontanus
mini pellia
blyxa japonica

Still have to wonder why the plants seem to be stagnant...
