Your plants look really unhappy......

At 94 degrees you're really cooking them. I can't tell you much about growing in soil as I grow hydro but I certainly wouldn't worry about anything else until you've solved the heat problem since you can't even say which of these things you are seeing are due to heat stress and high humidity.....until you fix them and see what happens.

Keep in mind....I'm not saying you don't have other probs......you probably do but I don't know enough about soil to help you.

Try this link and see if it can give you any tips. Good luck.
