look ok ..
tho I would start seedlings in cups and repot in to bigger pots .. hard to water big pots with small seedlings with small root net ..
and weed also stretch ther roots out .. so they dont use 30% of the middel soil .. if grow in smaller pots fist it will have a hugh root net in the middel of the final pot/bucket .. just consider it in the future .. atlest you got big pots

hopefully also with big drain holees in the bottom ?
about the light .. with autos .. I would mainly choose 2700K and 5000K bulbs ..
and I would also get/buy/make a hood of some kind .. for reflextion use 10-20$ on maylor boath for the hood and the walls/around the plants ..
etc. if you make a wide hood .. lets say 2x3 feet you could let maylor hang down on 2-3 sides ..
here is what I have going on right now (T5HO tubes)


got maylor on boath sides of the fixture (on the wall and hanging down from the fixture as a curtain)
one end ther is a fan .. wher my intake is .. bloweing fresh air at the fixture/plants .. other end my tube from my outtake vent.
trick with clf and tubes is to keep them close as penetration is ther biggest down side .. 2-4 inch`s away seems to work best for me .
but most importent is to train/top/FIM the plants to get em bushy and keep em low and even .. so most of the plant is right under the light ..
