Little help, please!

So these ladies are 9 days old. They're autos. They stretched a lot bc of a lack of light for a short time. Had to plants them in cups due to multiple screw ups in n my part. I've got sunshine mix #4 and down to earth 4-6-2 that I'll be using when transplanting. I'm really worried that they're not doing as well as they should and could use some help with how and what I should do with them when transplanting. I've done a few runs but never autos, so I'm wanting to get the best results. Any assistance and/or advice is greatly appreciated. Thanks fellow growers!

Theory :

Your sunshine mix is an inert medium, not a living soil. To best utilize dry amendments, especially stuff like Dr Earth that’s made stuff like feather meal and kelp instead of chelated nitrates and phosphates, you really need a living microbiome to do that work of breaking it down for the plant. Something like sunshine mix doesn’t have a bunch of organic material, inoculants, or colonized micro life in it to help do that work. The plant itself can’t break down organic material, and it can’t eat anything unless it’s “ready to eat” and freely available. We either use chemically-chelated synthetic nutrients that are readily available, or build a living soil and have the microbes break down more complex organic foods for the plant over time. It’s generally recommended to add something like compost or worm castings to a ”plain“ mix if you want to feed the organic route. This supplies that early boost in micro life and adds a buffer of organic material. Its also advised to let that soil ”cook” - letting the microbes feast and break down all that food before planting. A good colony of micro-life will also be able to eat through additional organic feedings like topdressings, and the microbes will self-adjust the ph into their desired range.

I've got a big bag of worm castings. I've also got a rooting myco as well as an instant compost tea myco. I'm not sure if I've got time to let the soil cook. They been sprouted for I think 8 or 9 days now. I do know if I let the root structure get too established in the solo cups, they'll be too stressed to transplant with best results. My down to earth mix and I've also got some gaia green to m going to add a spoon, should be a good start. It also has been with my photo transplants. I don't have time/funds to switch nutes right now. I'm just trying to get the most with what I've got and I think I can get a good result if I act somewhat quickly.

Heres my blend of nutes

The rock phosphate and langbeinite should be available immediately for P and K, but you don’t have any immediate source of N. Bloodmeal is pretty hot, but still needs to be broken down for your N. Alfalfa is also good for N and K, but same deal, needs to break down.

Well, with what I've got available, what would you suggest to help emnout for that couple few weeks to get things broken down?

Also, do these plants look bad for being up for 9 days or so? I feel like some other grows have been much more established at this point.

They look overwatered and stretched of course.

What are the temps in that “ room “ ?
They be lagging because of that.

A little over 70. And they're only like sprayed over with water once a day. Like a mist. I has to buy a shitty bag of soil to germinate and sprout them in. And I think the humidity is about 60. A little low but not terrible. The root structures are looking good besides 1 that has been bad since the beginning. I know they're stretched but I have never been bed about watering. It's a new environment from my other grows. A 4x4 tent, to now a room of about 10x12. Not talking shit, I really want them to recover. I've grown some decent plants, but these are seeming to be a bit different

Alaska fish fertilizer 5-1-1 has some immediately available nitrogen, if you need a quick organic solution. I just add a bunch of castings to whatever shit soil I have and that keeps little plants going until I need to put them into 1 gallon pots.
