Yeah I'm hoping that was the issue. I lowered the dosage of fertilizer to try and get rid of the algae which probably hurt it even more instead.
Both my nutrients and lights have been increased/fixed so hopefully the issue will be fixed soon.
Although my plant is about a year old now, it was quite small until a few months ago because I used to dose the tank very
lightly with fertilizers.
Once I changed my substrate it exploded and looked great. It slowed down on the frequency of leaf growing but kept the size after a while, and finally, started growing smaller leaves just a few weeks ago. Probably due to my sudden growth of green water algae.
My tank is a 20gal tall so it simply hasn't had the chance to send anything up to the top yet. I don't trim it as I don't have the need to, and although its leaves haven't melted up until this week I only cut the dead ones off.
If I did have leaves going to the top however I would absolutely let them grow as I need some more shade in my tank (in fact, due to it not growing any lily pads I just recently bought some frogbit for some of my plants that prefer shade).
Yeah I hope that's not the case. The melted leaves didn't melt any further surprisingly, so the very inner part of the leaves and stems were still intact. I did cut the leaves off last night just because the melted parts of the leaves were quite ugly. The early stages of melting on the bigger leaves hasn't expanded which is some slight relief because my fear with the others was how fast the melting happened.
I have dosed more fertilizer and a root tab close to it last night (the other tabs were placed a bit aways from the plant, was more meant to "share" between the other plants near it) so hopefully it'll grow a new leaf and get back on track in a few weeks, thanks again for the help
