Can anyone help I'm at a total loss. My amazon sword leaf tips turning brown, an only the leaf tips. The rest of plants are flourishing. Water parameters are are stable ammonia 0, nitrite 0, Nitrate 5, ph 7, phosphate 2ppm. Root tabs (tnc) added every 8 weeks due to 5" deep gravel substrate. Liquid fertilisers tnc complete 10ml x3 per week. Potassium 10ml x3 per week. Liquid iron 5ml x3 per week. Fluval plant 3.0 runs at 9hrs but peaks at 100% for 3 hrs. Co2 runs for 8 hrs which achieves a 1 point drop on ph from 8 to 7. Here in the photo is an example.
