In answer to your previous question, I'm with SBG, just leave them alone apart from watering

There should be ample nutrients in the compost you bought to last them at least a couple of months while they get settled in

I hate to add note of discouragement, but I can almost hear vine weevils signalling fresh food has arrived

It is a sad fact that strawberries in pots, like tuberous begonias, are very prone to vine weevils.
If you spot the plants flagging a bit next year I'd check that first
