glosso yellowing from the bottom with black / greenish dots on it
i have a eheim 9 gallon tank with a couple of batch of glosso planted in eco complete. after having to trim about two weeks ago due to its vertical growth, ive noticed almost all glosso i planted in the tank starting to turn yellow from the bottom up (getting worse); ive also noticed that the older leafs closer to the substrate not only is yellowing / melting away but also has these black and dark green-ish dots on the leaf itself... can someone help point me to the right direction on solving this problem?
lights = original eheim 13 watt top mount LED on 7 hours a day (prior to trimming it was on 10 hours a day)
running dyi c02 setup
1/8 tsp KNO3 3x a week
1/32 tsp KH2PO4 3x a week
1/32 tsp K2SO4 3x a week
1/32 tsp (2ml) comprehensive 3x a week
50% water change every week (sunday)
thanks a lot! any help would be appreciated!
