I like your setup it’s very nice!
They look very young and a tad dry. At that stage I would put a few drops of water in the bottom of the jiffy pot and let them suck it up until they look moist. I would keep my led light at least 36” away.
then you can check on them every few hours to see how they are responding
For now I would wait on adding anything to their water, you can place them in the pots you have ready in your tent after you moisten them.
You just dig a little hole big enough to fit the whole little peat pellet , squirt some water to moisten the soil and put the pellet in the hole and move the soil to cover the pellet and some of the stem and squirt some more water the outer edges. This will give them their permanent home and they will be very happy!
There are nutrients in the soil that the young plants will feed off. Do you know what kind of soil it is?
I have a hard time throwing out any plants too! I don’t know if it’s going to make it the little nubby one but probably not because it doesn’t have any leaves.
I looked up the Jungle Juice trio that I think you have. It looks like a different bottle for vegetative growth, blooming and then a bottle of micro nutrients. Is the the PH perfect type? I would not combine them all in one bottle yet. Learn more about them first because you can do that with some and not with others.
Here is a link to the PH perfect Jungle Juice trio(I hope this is what you have)
Grow Micro Bloom hydroponic fertilizer specifically designed with pH Perfect plant nutrients technology to avoid pH-level problems in your grow room.

I myself am not familiar with it but that doesn’t mean anything because there are tons of nutrients available everywhere!
I think this is good for now. As far as the fan goes not sure you need it yet. It will probably cool things down and they need it warmer right now.
