Help on 4 inch transplants Ghost pepper,tomato.

[mick5500]

I have some tomato and pepper seedlings that are doing well. They are Trinidad Scorpion and Ghost pepper(Bhut Jolokia) and some Bloody Butcher Mary Tomato
getting ready to transplant to 5 inch Planters Pride Grow Coconut Pots, or some 1 gallon fabric grow bags.

I purchased these form Hirts Gardens. I tried to grow the Ghost Pepper from seed but they never germinated
The Trinidad Scorpion pepper plants I have had a month and if they are in the sun for more then 45 minutes they wilt.This is at 9:00 am. They bounce right back though, but it has been a month, Pictures are attached

My question is what potting mix should I use for all these. I used Miracle potting mix on my other plants and they are not doing well.
Also should the Scorpion still be wilting after a month. I move them in and out to shaded sun a couple times a day.

Thanks for any advice.
