1st time grower need help planted seedlings 5 days ago in MG potting soil can is it to late to switch soil to organic?

I'm a new grower and stupid me bought normal miracle-gro potting soil then after doing research I've found out 95% people have been saying never use MG, first I used old potting soil that my parents had 4 days ago day 1 and 2 was 30°c the 2nd day the leaves started going white so I switched the soil to MG so 2 days ago I planted my seedlings in MG one day was sunny and hot next day which was today it rained on and off lightly, so is it to late to change the MG soil for something different? They are starting to look better in the MG potting soil( btw it's not MG moisture control) but still if it's not to late I'd want to change

Here's photos of both hybrid plants sorry about lighting

I'd leave them for a couple of weeks to get over the shock from the 1st transplant, then repot if you feel it's necessary. It's not like they won't grow I'm MG.

Awesome thanks man, yesterday and today it's been raining its 50 out right now should I leave them outside at night under my patio or bring them in at night ?

heres some better pics
