I've been growing plants for a long time now and this is the only plant that has ever given me fits and is still giving me fits! It's stunting like crazy. Actually, half of the stems are stunting, the other half have smaller new growth. What am I doing wrong? All of my other plants are doing ok. What gives?
Tank: 29g
Lighting: 2x65w 6700K Coralife fixture
Carbon: pressurized CO2 and Excel
Nutrients: 7-8 ppm KNO3 eod, 1.5-2.0 ppm PO4 eod, 10 ppm K2SO4 eod, 12 mL Tropica PNL eod, Flourish Iron 2 mL daily (eod = every other day)
Substrate: ADA Aquasoil /w Powersand + Tourmaline BC
Water: 75% or better RO, the rest is tap. I know the KH is really low, the pH is very low, and I don't have a reliable method of testing the GH.
I've never had a growth problem before with this similar setup (substrate and 100% RO water), so I'm doubting the GH as being an issue. I also doubt it because my other plants (Toninas, various rotalas, etc) are doing well. What is it with this plant?
