They look perfectly good and ready for an HID to me!

Still not mature enough for nutrients.

As a suggestion, you should get a fan that oscillates (!), and set in so it blows back and forth. That forces the plants to strengthen their stems.
And once you get that fan, you will start blowing that loose top-soild all over the place.
So THEN what you can do is get small white rocks/pebbles/diamonds, and spread them over the top of the soil.
Water goes in. Soil stays put. Gremlins stay underground.

Nice!
