OGC 800x800x2000 first grow

Ok so first real grow kicking off, started about 6 weeks ago with one bag seed to monitor my conditions and see what i was facing, that plant officially dubbed "planty" seen more shit in 6 weeks than most would put any plant through in a season. Chances are its gonna die but taken some remidial steps to tryand save it but its possible root rot has set in.

Any ways currently have 6 seedlings 2 days old under the 130w cfl. Hopes are to run them inside for about 6 weeks till were a little closer to summer then they will be transitioned outside. Then ill work on getting some clones into the tent.

Tent; 800mm x 800mm x 2m
Lights, 130w cfl for seedlings, 600w MH superveg for veg.
Soil; Richgro potting mix, 30% pearlite
Nutrients; House & Garden soil A+B, Floramax Ca-Mg, Ph , GreatWhite & Ryzo organic root booster.

26th nov; day 1 of seedling stage

Dusted the jiffys with a little Great White and gave them a little more soil to root in.

Nearly 5 full days without as much as opening my tent, fair bit going on, work, family, training new puppy, gym and i honestly forgot about it.... whoops.

Two end seedlings are trash they spent about 4hrs in sunlight before going into the tent a week earlier and their roasted. None the less the other four are flourishing and will they will come out of the dome tomorow and upgrade into a real pot.

Looking foward too seeing the root growth from the past week theres already some chunky whites protruding from the drain holes in the tray now they just need room to spread.

Upsizing, root structure from the smallest of the 4 viable seedlings pictured above. All hit with a healthy dose of great white, and repotted in the same soil/pearlite blend. Burried the stretch and watered with 1L divided between them, tap water, less than half ml of ca-mg, phd 6.4. Back in the tent just on the timer for a 6hrs dark period. Lights on and all 4 plants were drooping but 10hrs later their perked up and all turned inward to the light source.

Bit of damage to some lower leaves on one seedling after transplant, instructed to leave it and just monitor and aside from a little discolouration not bothered by it, presuming its light burn amplified by droplets on the leaves. Aside from that overall happy, 4 days growth theres not much stretch but theyve all stacked an extra node. Light water today no nutes ph'd 6.2.

All seedlings seem to be getting a little yellowing on bottom sets. Assuming their still in their seedling state they shouldnt have an issue with somewhat higher humidity which got to 60% last night with the aircon left on by mistake. So ruling that out, leans me toward ph imballance or underfeeding so todays feeding 1L tap water, 2.5ml H&G soil A, 1ml Ca-Mg, ph'd 6.0.
