My recommendations would be to keep the humidity above 60% at first, control the temperature so it doesn't drop below 20 or rise above 27, and if the temperature allows, I would lower the light and bring it closer to the plants.
As for watering, since you put a large pot that will be the final one, gradually increase the watering. Don't forget to also check the pH of the water, it should be between 6/7 since you're using soil.
Best regards and happy growing, if you need anything, just message me and I'll help you out.
