It needs a bigger pot. I think you’ve mentioned pests is some other threads. If you have fungus gnats or other soil bound critters (which seems likely based on what you have described), the small pot creates even more of an issue. You’ll continue to have issues as there’s not enough soil to support the root system. If you have fungus gnats, they eat roots, and the more roots the less they can damage. Limited space means limited roots. They’ll continue to overheat also. They need to be transplanted soon though. My outdoors are now showing sex. Flower season is on outside. Transplant to a larger pot asap. Or don’t.
