Yes I agree that your soil looks a little dry. They don’t like sopping wet but wet is essential for those little roots. I would water these mostly around the edges of those little pots to encourage root growth. Try not to get the little plant wet when doing so. Your little makeshift reflection house with plant bulb should work at this stage but your SP1000 can also easily handle the job. If they start to stretch remember they are looking for more light and you should act quickly.
