Pics would be great thanks. I kinda skipped over the whole is it ph section so idk if youve transplanted yet but i have an idea on what you can do to save them. Growing should not be this complicated. Anyone is welcome to comment on this idea as well.
1st. Ive read the link to the grass city soil mix you used. It looks like that could be part of the problem right there. Wayy to complicated and if you messed up on measuring one of the 40 ingredients in there your finnished before youve even gotten started.
2nd. Your 400 watt mh bulb at 24 inches above a two inch plant. They are going twards the light as we speak

3rd could be watering issues by the droopyness but that 400 watt should be able to dry up a cup filled entirely with water in a day so maybe or maybe not.
Heres what id do if you were to ask me to look after your plants right now. First id go and buy some good ole chronic grade dirt from your local hydroponic store. I like ffof or happy frog but if they look to be burning which they do and you have the choice i would personally pick happy frog because its not as hot as the ffof.If thats not available to you then miracle grow will have to do. Id then transplant them into half gallon or around that size containers. That way if they do come back around and the mix is wrong in the dirt concoction youve created, they will have a chance to live eventually. If the dirt is wrong your kicking a dead horse, get it?
Secondly i would move that blazing hot high intesity discharge light up to four feet over the plant. Trust me, thats more than enough light for 20 plants that size. It will also help keep your temps from reaching 86 degrees right?
Finally i would water them as i alway do with some great white for their first watering and then make my way to the fridge and make myself an almost lethal bloody mary and chase it down with a 6 pack of imported beer, well maybe 8 or 9. I would pass out later that night and snore in my girlfriends ear but i would be confident that now my newly adopted plants are not going to be fried by gamma rays or forced to live in a martian environment. Then i would repeat the whole getting drunk and snoring in the girlfriends ear thing day after day until the plants recover, using only water to hydrate them. Good luck
