Plant Deficiency (Ludwigia + Rotala)
Hello guys, long time lurker here. Been trying to diagnose what is happening to my plants, and never really found the right answer online (and on Reddit).
I have a 5gal planted tank for about 5 months now, params are 0,0,20 (20-40 nitrate tbh the colors are similar). I am dosing Tropica Spec, Premium, alternate days, 1.5ml each. Also dose about 0.7ml Excel daily. On Saturdays I don't dose, and on Sundays I do a 40% water change. Lighting is a Chihiros RGBA+ which is pretty decent. Filter is a Shiruba XB303 which powers through 360 Liters/hour. Tank is stocked with a betta, 5 amanos, 2 SAE and 2 otos. They seem to have too much algae to eat tbh.
From the beginning I had 6 stalks of Rotala H'ra, which grew into a forest right now. I am pleased with the vegetation but I think the leaves aren't doing so well. I couldn't find out what is wrong, some say manganese, some say calcium, while others say iron. About 5-6 weeks ago, I dumped some Ludwigia Palustaris in as well, to see how it will fare. And it turns out the leaves have a similar symptom.
I've also included a semi full tank shot, with my monte carlo carpet and mayaca fluvatilis, some bacopa (new) and some pennywort (new). Overall I think the grow is ok, just the bad coloration on my leaves. Any advice from the experts here?
