2 things wrong with my plants, please advise.
the leaves of my anubias, are curling and cupping. I read that this is a deficiency in calcium... Can I just get calcium suppliments at the pharmacy and crush it and put it in the tank?
small yellow bloches?sp are showing up on the leaves (anubias, lutea).. Is this a deficiency in nitrogen? my nitrate is at 20-25 ppm, phosphate @ 4 ppm... I dose a small a mount of MgSO4 just in case Mg or SO is missing.
i just did a 1/4 water change to replenish some nutrients. and just added a capful of trace.
it's a 29 gallon tank with 2.5 wpg, 9ppm CO2.
