Lower leafs of my Limnophila sessiliflora are turning brown
Is this normal?
If not, what can I do to help it. I am dosing P, Flourish, and Flourish Iron. My N is at 10ppm, ph = 6.0, kh = 7.0. I use Flourite and Flourite Red for substrate, 10# inject CO2 and 582 watts of PC over my 100 gallon. Oh, w/d filteration.
Also, the lower part of the stem is brown as well but the higher part of the plant is very big, healthy and green. Is this a sign to trim the plant?
