BC Northern Lights Bloombox first indoor grow

Hey rollitup! I purchased a bloombox about a month ago and I've been having some problems lol...I started off by soaking 3 fem seeds from greenhouse in distilled water over night. Morning came and I moved them into a moist paper towel, all had cracked with showing super small tails. Soaked rockwool in 5.6 pH water for 4 hours, moved the seeds from paper towel to rockwool(all had 1/2 raproots)...threw the cubes in my clone dome under 125w cfl for 18/6 lighting... 3 days later they got to 2-3"...after 7 days I had to transplant becuse roots were coming out ends and sides so I moved to the veg chambed (soaked 3" rockwool with 1ml sensi grow a+b and voodoo per gal) below and removed the tray...now for some reason all three seedlings are doing terrible and I believe are not going to make it...I am still hand watering to establish a root system...sometimes the temps can reach up to 85F! that has to be what it is right? what's the lowest good temp seedlings can handle??

no one??? I thought this was the site for help?

1 - The starter leafs for when the seed sprouts are suppose to die but it differes between people when the starter leafs die.
2 - Those temps should be around 70F witch is around 20C
3 - Are you doing Aero, Flood and Drain or DWC?

Don't forget some times its just the luck of the draw that the seedlings don't make it.

Also, i think one of your problems is you should'nt have used any nutrients for the first few weeks during seedling stage, seedlings provide themselves with all the nutrients they need through their cotyledons, you may have burned them badly when you added the nutes to the rockwool.
However from the pics you have posted..they look perfectly fine to me

Yea they look a little over watered though. As for the nutes if you have regular B-1 Thrive you could use 1 to 3 drops for 1/2 to 1 cup of water. Its weak enough that its not going to burn your plant but just enough that they can feed off of the nutes. I've been feeding my plants since they got a taproot and never got nute burn or any thing.

Let them be for a while and they should bounce back. Don't feed them again until week 3 and start very small. Northern Lights are notorious for not needing to be fed much.
