Hi everyone, last week in my 15 gallon i started fertlizing (experimenting with Tom Barr estimated method). Half a teaspoon of potassium sulphate & epsom salt, about 7ppm of potassium nitrate per week and 3 drops of PMDD mix (minus the nitrate) per day. the water here is very soft. According to the local water company, the tap water has an average hardness (GH) of 21 mg/L (1.2 dH) and and average alkalinity (KH) of 11 mg/L (0.6 dH). ph is approx at 7.
i have 30 watts of light from a NEC triphosphor bulb and Soil/ gravel substrate. no co2 supplement at the moment.
well a few days after a started fertilizing some leaves of my hygro polysperma went kinda white and some were bronze and developed patches of green but the leaves of other plants stayed basically the same colour. also growth has stopped and the leaves of hygro polysperma and difformis appear to be wilting. growth was better before i started this fertilising regimen.
does anyone know wat the problem is?
