You are looking for trouble avoiding K, P. & N. If you are running pressurized CO2 & your lighting is up to speed you will be making an algae farm without The big nutrients. Plants need proper nutrients to compete with the algae. Algae can operate with very low nutrient levels & out compete your plants. It is a myth to think that keeping low Nitrates & phosphates will keep algae away. It is actually the opposite.
I would dose dry ferts , which when mixed are really liquid ferts. The tank needs to stay above 10 ppms of Nitrate at all times. PO4 should stay between (.5-1.0) ppm at least. K every other day at least. The tank will need good flow & filtration to keep BGA away as well. The lighting needs to be between 6500-6700k or your looking for trouble know matter how you cut it.
