Well I posted a while back about my nana leaves curling and the consensus was that it was getting too much direct light. I moved it underneath a sword so it's fairly well shaded, but new leaves continue to curl forward (not the normal unrolling). I've also noticed two of the older leaves developing a crack with a hairline of brown. I am dosing 1/16 tsp KNO3, 1/16 tsp phosphate (to deal with some green spot algae), and 1/32 tsp potassium every other day, with 2 mL of Flourish on the off days. 50% water change weekly and 30 ppm CO2 (by drop checker). It's a 10g tank with 28 watts of 6700k light. Any ideas? If my description is not clear, I can post some pics tomorrow. Thanks!
EDIT: Ah, yes, my substrate is straight Flourite.
