Banana Mango - First Time Grow

The plants have exploded with veg all around them. They have taken to the pots insanely fast and had no problems when transplanted. My problem child is still getting some twisting and yellowing. The leaves feel thin even though they’re green. It’s most likely to much heat, but can’t do much about the sun heating up my house during the summer. I’ve moved the light a few more inches to give it some stretch as well as take some heat. Moved a fan in its direction as well to direct some of the heat away. Everything else is good, will start to defoliate soon and will be removing a plant for practice reasons.
