Watering newly transplanted plants

Whenever you transplant into a bigger pot, the first few waterings the established root ball becomes drier way faster than the new soil. I'm using a new soil this summer for outdoor called empire builder soil and it's a very thick mix that holds a lot of water, as I live in socal and it gets very hot down here. I transplanted over a week ago from beer cups to 4 gals, and the new soil is still most but I can imagine where the roots were before is dry and needs more water. My question is should I wait until it's dry throughout the pot to water again, or water now. Also is it bad for the soil and roots to be hot? I've been putting the plants on the turf in my backyard to try and dry the soil faster.

Dude! My homie wraps white paper around his pots and it cools it well, rather than black which absorbs the sun

Anybody have any suggestions?

Let it dry out more. The roots will not grow into new space if there is water in their current space. They grow to seek out moisture.

If the surrounding soil holds water, your girls will find it.

T.H.C im assuming this because when they were in the cups they dried out every couple days cause there was a solid root mass drinking a lot of water even though they are not drooping at all and dont look thirsty, im just assuming the roots toward the middle of the original beer cup soil are dried because its been so long and the soil i planted into has barely any coco or perlite whereas the soil it was in was a very aerrated mix

also so should i keep the plants off the turf and put white areound them to keep them as cool as possible

Take it from me, I transplanted super tiny (3-4 cm) seedlings from Dixie cups/beer cups into country crock butter dishes, mostly just BC I started them in miracle grow six month soil and wanted it changed. They took the transplant well, but now they are in much bigger containers now that take 3-4 days longer to dry out, where the other ones only took a day or two.

I was over watering really before the transplant, and my new soil holds water like crazy so I added some perlite--definitely really helps. You also want to make sure you have great drain holes in the bottom so the soil dries out faster and you can water more, and your roots will still search longer.

Long story short, I've had more growth in the passed 3 days then the 10 days before that, BC I've been giving the soil time to dry out almost completely.
