They seem fine but it's a bit difficult to tell precisely with that lighting - 1ml of grow however is relatively high especially so early on, for reference I start with 0.5ml and never go higher than 1.5ml for autos. I would expect them to be slightly bigger by day 13, so I would consider adjusting the lights, maybe they could be a little closer or if they're dimmed, turn them up a bit? Excessive nitrogen can also slow the growth so that's also something to consider, especially as they show a bit of a claw.
