    Generally, when you pot up, it should only be an inch or two larger of a container. My guess is that much of the soil remains too wet, since there are no roots through it to pull out more of the water. This can cause slow growth.

    Fertilization is important as well, but only if the plant needs it. A soil test will confirm this.

    If you think your plant is getting cooked by the heat, it's alright to move it into partial sun, so long as it gets sunshine most of the day. This plant doesn't respond well to over-watering or under-watering, but a more serious issue could be a fungus.

    This infection is likely because of the aphids, and overwatering in combination.

    From here, a fungicide will be necessary. This article will help:

    The soil in the pot with yellowing leaves is probably not giving the plant what it needs. You should consider repotting that one with a fresh soil mix. This article will tell you what this plant requires:
