Water parameters can vary a lot for a planted tank. The much more important thing is the amount of light you have. The more light, the more you need CO2, and the more light the more you need to keep the CO2 consistent, from day to day, as well as the more CO2 you need. Also, the plants' growth rates are dependent on how much light you have, so the more light you have, the more nutrients the plants use per day, requiring higher and/or more often dosing.
Since you already have an algae problem you probably are not using CO2 at all, or you are using too little and to inconsistent for the amount of light you have. What lighting are you using - type of lights, and how many bulbs, and how far from the lights to the substrate?
