First, increase the distance to the bulbs, seedlings are very sensitive to the heat put out by HID bulbs.
Second, stop all feeding, 11 liter (3 gallon) of soil should last you for several weeks without needing additional nutrients. Wait until you see the first signs of deficiency before adding any more. You probably have 8 weeks before you'll need to add nutes.
Third, I know Biobizz says not to, but bring your pH down to the correct range of 6 to 7 (6.5 is ideal), it does help. Actually I've had leaves curling up like yours due to high pH.

Hi there! Well this is a common issue : dryness/under-watering. You can try to increase the light/plants distance (so they take longer to dry and get less heat from the light) and water them more often (ideally at night). Also, it will be a good thing to increase relative humidity in your grow room, I'd recommend you to buy a MistMaker, they're working great. I'll be around, keep us up-to-date, and good luck with your babies!
