stick to it, you'll be right. you're learning about your soil mix & its watering, depending on the growth development - make adjustments as you go, if need be. add coco or more perlite, whatever etc. get your grow medium right for your conditions/preferences.
i can see you watered just around the plants, as recommended when watering small plants in large pots. the suggestion is to start in smaller pots and gradually re-pot, as they get root-bounded, into larger pots, because it is harder to overwater in smaller pots.
when you get the conditions more suitable, the plants will reward you by their response with healthier growth. they look a bit battered presently, but they can recover quickly. also, they should get larger soon, when you'll probably find it easy to water.
