Holiday grow! 2nd grow!

Hello all, well i decided id have a grow journal, im still in the middleish of my first grow so im still preety inexperienced. Anyway. my only sprouted seed was planted on christmas day, and the other two planted on christmas day are comming through the soil now . The other 4 where planted on new years eve.
so these are all holiday babies!! They are all good bagseeds so im just doing this mostly as more practice. I have a feeling im going to need quite a bit of help during this grow so all the help i can get is greatfull. I will be posting pics around everyother day to keep myself and anyone watching updated. Thanks for comming and enjoy

First off everyone is on 18/6 light cycle
My grow box is 2 1/2ft wide, 1 1/2ft deep and 1 1.2 ft high, once they outgrow this box they will be moved to the upper box which is 3ft high, 2 1/2 ft wide, and 1 1/2 ft deep.

For my seedling i have 4 23watt cfls on them, 2 are warm and 2 are cool. i can add more when the time comes. there is a fan inside the grow area, just circulating the air, and the temp is 69F MIN - 83F MAX. They are all in solo cups for mow with 50/50 perlite/soil mix.

one of my christmas planted seeds broke surface on 12/30 here is the pic, so far she/he is looking healthy and happy.

I'm sure you'll find plenty of advice on here and help throughout your grow cycle.

HAPPY

Here are some updated pics of the grow the other 2 christmas babys died but all the new year babys broke the surface today . Chrismas baby is doing mightyyy fine.

The only thing i see weird is that one of the New year babys root looks like it came out of the soil, then back into the soil, its the last pic ( its the white thing). Could someone explain this to me? should i be worried?

well the plant with the root that went back into the soil died but the rest are doing well so far. working on a humidity dome. are they too old to be put into the dome?

Well some updated pics. The lowest leaves ( sprout leaves or something ( forget what they are called ) are burning i think on the tips, i dont think its nute burn since i havent added any yet, but im thinking it my be heat burn but the highest temp is only 85, i dono the real leaves arnt burning so i wont worry about it right now. Also NY 2 doesent look to be in great shape, over watering maby? Well if anyone ha any answers please post, now no more rambling here are the pics!

A few weak Ny babies died over the few days, but all the other NY babies are doing greatt, working on the 3rd node. The xmas baby is looking a bit on the weak side, i transplanted her into a bubbleponic setup, dono how its ganna go.

Any help about the bubbleponics ( first time ) would be a great help +rep

here is how the girls look in the bubbleponics setup

some more pics of the three thats left, the xmas one died a few days ago, my seedlings are drooping really bad and they are yellowing, anyone know what the cause could be? Pics below
