I don't know if it's the same where you live but many plants bought here have been grown on quickly in very protected conditions and are 'soft'. They need introducing to reality slowly. I'd pinch the tips out of that and make sure it's not completely dry. Same with total sun, it may never have seen that before
If something is growing in a pot it will need to be watered where it might not if it was in the ground. That inside pot look like one of those that breaks down when it's planted (in theory) that only works if it's wet.
Apart from watering in I have never watered a lavender, I don't like to see them lush and green. But mine aren't in pots.
