I dose Ez green once a week. my lights are on 10 hrs. My other plants are doing great but all three different Anubias turned black on the leaves anyone know what’s the issue?
Too much lighting for too long of a period. Hydrogen peroxide will kill off algae growth on leaves...either squirt some H2O2 onto effected area with a dropper or remove plant and use a spray bottle.
Problem will come back till you find that balance of ferts & lighting issue.
Unless your intentions are to breed those MTS, they’ll get out of control fast.
