I would move your light closer, I don't know the intensity of your light but that looks starved for energy.

More light and add some calmag
Besides that they look pretty good

To be clear...18" above the plants
Worst case it will start to leaf burn and then just raise it 6". If it has a dimmer, dim it a little for first few days. Otherwise you are paying for all that light to barely reach (and feed) the plant.

(1) You need a light meter to be able to tell how far away to have the lights. Young pre flower plants need about 300 PAR. 20,000 LUX.

(2) The plants don't look bad. One slightly yellow indicating low nitrogen may be low. I give my auto veg plants a dose of Fox Farm "Grow Big" if a plant is yellow. At half strength.
(3) They like to have a chance to dry out the roots a little between being watered.

Yeah let the soil go a few days between watering. Better to water more and skip a few days until they get going.

Could be water issue too but they look alright just a little yellow on that one plant. So she's looking for nutrients.

AUTOs anything could happen. It's REAL important with AUTOs to get a good size root ball early on.
