Any help/tips would be greatly appreciated

1st ones orange habanaro second ones mammoth jalapeño third is cayanne and she's not looking so great at all the soil was pretty dry I spaced them more apart and watered as I can't get them in to separate 5 gallons till Friday unfortunately feel like I spaced them decently and watered decently (just hope I didn't overwater) but I did a tiny bit extra because im in zone 6a northeast pa and it is real feel 90 here today probably well over 100 in my temporary greenhouse from Amazon it doesn't have a vent and when I had the flap open for even 20 minutes I had to get 3 flies out so not sure if that's the best idea lmk or if I should just keep steady water like I said newbie grower here just looking for advice for a somewhat decent harvest not sure if I wanna top them when I get them in the 5 gallons kinda nervous about that aswell thanks for reading though
