I have some narrow leaf micro swords in my tank that have been spreading fairly nicely, many of the chains of runners are a foot long, or run into the wall and keep cruising. Basically the growth of the plant is seemingly good. I dose NPK, Trace, Iron, and CSM. I also inject c02. Tank is a 56 gallon, 30x18x24 with a 175 mh
pendant about a foot and a half above the tank. The other plants pearl, and I chop handfulls of clippings out every week. Little green spot algae on my java fern, but what can you expect I suppose. Anyway, the micro swords have some kind of fuzzy brown, perhaps a hint of green algae growing on it. If I stir the substrate the algae will hang on to the dust stirred from the eco complete. I added a Koralia nano powerhead in the corner of the tank to increase water flow to see if perhaps that was the issue and it has not happened. And allthough I say that they have been spreading well, the vertical growth of the mother clumps have halted in the past couple weeks after I trimmed them down, but are not dying or showing signs of lacking nutrients or lighting. Hope that was lucid enough info, I would really love to get to the bottom of the issue.
