Doubtful... looks like a normal deficiency of some nutrient. Algae has started to get a hold now... the edges of the sword leaves are going darker with some very fine thread algae developing on them. My cabomba and pennywort are untouched at the moment.
I have cut my lighting back to 8 hours and will continue my dosing regime with increase nitrogen. Seems unlikely with my stocking of fish but possibly nitrates are being depleted as I change 25% of my water twice a week and maybe my tap water is low in
no3?
