Excel overdosing and plant coloration?...or lighting issue?
I have been dosing excel a little over 2x the recommended amount for a few weeks now and it has definitely kept some nasty algae at bay. However, I have noticed that plants that were starting to turn red as they neared the surface have reverted and have started to lose their red/orange/pink. I'm dosing per EI with extra iron, co2 that's nearly enough to gas my fish, and 4 t5ho lights over a 20 long should be more than enough to redden plants right?
I only realized today right when I was about to pour in the excel that it may be the problem.
So my question is, can excel cause harm to plants like Ludwigia repens, Limnophila aromatica, Naesae sp red, and Alternanthera reineckii? I know it can and will melt a val and some others, but it didn't cross my mind that about these other plants that have slowly been losing color.
I held today's dose and plan on stepping back to the dosing on the label.

Reason: could be a different problem.
