Plants not doing great, need fert advice
I currently have a 29 gal low tech heavily planted tank. Almost all my plants are low care plants. (Javas, Anubis, etc) some are doing great and flourishing and others seem to be starving. Some leaves have small holes forming but the most common symptom I am seeing is very dark spots ranging from dark green to black. A lot of the leaves are sort of curled over at the edges as well. Another thing I noticed on my faster growing more delicate plants is the older leaves seem to turn reddish brown and just disintegrate. I know I've got some serious deficiencies I need to get on top of.
I am using miracle grow organic capped with regular black sand.
Lighting is 2 finnex ray2s so I can't imagine lighting is the issue.
I am not at all new to aquariums but I am somewhat new to heavily planted tanks with soil, just wondering what ferts/ minerals I need to start adding with the symptoms described. I was thinking of starting flourish along with flourish trace.
