Monstera yellow marilyn, yellowing leaf, does anyone have any idea what could be wrong? Over or underwater ingredients or something else?

I know its normal for the older leaves to yellow as the plant ages. I already lost the two smallest leaves that had no fenestrations.

The lowest current leaf has started to yellow and brown as well. Its potted in a chunky aroid mix, under the sansi 36w bulb. I find the room it's in can get pretty warm, especially in the summer and I find myself watering my plants often. It was in a very tiny nursery pot that would dry out within a couple days, as it was mostly all root. I found that within a couple of days after watering the leaves would start to curl and droop and would perk up again after watering.

Since repotting about 2 months ago the roots have been taking over and are growing out if the new pot. I fertilize with MSU at a half strength weekly with distilled water but was wondering if I should switch to something else? It's what I already had on hand for my orchids and researched that it could be used for aroids but maybe something else would be better, I'm not sure. I also use Marphyll soil enhancer (which is a marine phytoplankton based fertilizer once a month). And I will flush it once a month to with plain water.

Room is pretty warm about 24°c currently and Humidity around 35% but can get higher in the summer, I usually have a fan running during the hot months.

I found that my gloriosum only started to do better once it was in self watering. It was also in a chunky mix, but in a terracotta planter and I was finding it impossible to keep from drying out too quickly. I'm not sure if I'm underwatering or over watering. Maybe I should add sphagnum or coco coir to help the media retain more moisture?

No signs of pests as far as I can see. Keeping an eye on it though. I think im going to be getting some beneficial insects for the summer just in case.
