Do these look ok for 19 days?

I've never grown under lights before so I don't know if this is an appropriate size for my babies almost 3 weeks old. It's just bagseed in ff ocean being fed nothing but plain water (ph always around 6. and sometimes a dash of superthrive after transplants and whatnot. I'm using a 324w t5ho fixture and they are about 6 inches away. I keep the lights on 24 hrs a day and theres a fan going round the clock and I rotate the plants in front of the fan. One of them looks a little stretched but the stem is nice and thick. The one that is droopy I'm hoping will perk up if I relax on the water. They are starting to stink a lovely lovely stink. I've thought about moving the plants closer to the lights but I dont want to cook them. The bottom sets of leaves are fucked up because I misted and the lights fried them but I cut that out quick. They each have 4 sets of leaves. Am I in good shape? Should I move the lights closer? Its already almost 90 in there and the humitity is up to 50 now that I have them in bigger pots...

they are looking good to me, light distance seems to be working well enough. 90 seems a bit high, but i am very jealous of your humidity.

looking good.
move the lamp higher to get a bit of stretch on them or they will end up like bushes.
and switch to 18/6 as this also helps upward growth.
i do 24/0 for 2 weeks and then switch to 18/6 for the rest of vegg.
then 12/12 for flowering.
your temps are a bit high also.
and the plant looks overwatered(droopy).
