Indoor Garlic and onions in trouble

Hello community! I have a whole garage full of garden plants and some are doing awesomely others seem somewhat stunted. Everything is under a 1000W HPS on a 18/6 timer so the plants are in Veg. (If all the plants are photoperiodic, which I'm not sure on. Due to the variety I have in one room...) Temps are High 85, night low 55 (F) and humidity fluctuates between 55% and as low as 15%. I have a circulating fan, a InfraRed space heater under the table and a radiator space heater by the garage door. (I live in Colorado and the snow just started in heavy!) I will say this; the canopy of the plants is very uneven I try to get the youngest plants and seedlings closest to the light and my sun craving plants on the table most directly underneath the lamp. The light itself is about 30-36" from the top of the table. (not exactly sure I'll measure tomorrow.)

I have several points of concern. My garlic and onions in both cases plants are very small and spindly, the tips are turning yellow, crispy, and falling down. I haven't pulled any up out of the soil to examine the roots and developing bulbs. I was using a Roots Organic Veg nutrient. But I found it smelled and was sludgy, so I'm just using pH balanced water (6.5) and have been for about 2 weeks.

Other issues; Spinach went into flower- can see little flower buds starting. WTF!??
-All of these next plants were germinated 2.5-3 weeks ago and are still not sprouting; Lettuce-(red romain and butter crunch) Carrots, Thyme, Marjoram, and Chamomile!
My Strawberries are really suffering as well, the leaves are really dry, browning on the edges and folding in on themselves also being eaten by fungus gnats, working on a solution, just waiting to make a trip to the hydro store... There is still new growth, so I'm really not sure what their problem is...

Any suggestions on any of these issues would be appreciated! Especially the onions/garlic and the strawberries. Thanks! And BTW, I will have photos up to really get a good look at what's going on, I just went lights out a few minutes ago... Please be patient and I hope I've provided enough info to get some starting points.
Thanks again!

starting from 1st to last. 1 & 2 are the garlics that as you can see are scrawny. 3 is the lemongrass, parsley and cilantro they're loving it! 4 has my pineapples (yes i'm in Colorado growing pineapples, call me crazy. Idc.) in the middle you can see the onions sticking up they are suffering as well. 5 & 6 are the same pot of strawberries, I have two more in the same poor condition. 7 is one of our peppers we have an ancho a mole and a anaheim we recently lost our habanero thought we would lose them all but it was small and pbly not getting enough light and had a traumatic transplanting. se la vie. 8 & 9 is a pot with buttercrunch lettuce and bok choy they are about 8 days from germ so they're doing awesome. 10 is a little better pic of the pineapples and the rosemary. 11 is green beans and they are doing awesome. I also have photos of my cucumber, leeks, tomatoes, celery, spinach, beets, sage, marigolds, a and non responsive but planted more butter crunch and red romain, thyme, marjoram, and I have 3 chamomiles, 2 are growing 1 is unresponsive. But these photos were downloading really slow and I already had 11 pictures up so hopefully somebody spots something and can give me some info. Also I have moved 1 of the pots of strawberries about 14" from the light hoping for them to perk up and so-far-so-good! I'll keep ya'll posted! Thanks for reading!

I'll take a stab and say Photoperiodism?
I was thinking onions and garlic are spring veggies that will grow with increasing hours of sun per day as opposed to less hours.
I would put a light mover up in the garage. May help with the canopy.
Found this page. Not sure if it proves me right or wrong.

Thanks, Onions and garlic are fall planters, they require a cold period before they'll form a bulb, in nature you would probably subsequently harvest in the spring after they have "woken up" and are taking in lots and lots of spring rainfall/runoff.. I'm just concerned about the formation of the green "leaves" that show up above ground. They seem very thin and are no longer reaching for the light; then, they're yellowing and spiraling to the ground! There is also little to no new growth forming... Do you think they're just ready for their cold period? We've had the onions since July and have done pretty well outside during the summer months but when they came inside after it started getting chilly they got really stunted... The garlic has not been around for as long. Had some garlic (from the store) in a hanger-NOT refrigerated. Mid-September the garlic was around for a little too long; broke some apart and what-do-ya-know there's a little green nipple sprout starting from the bottom of several cloves of garlic. I experimented and threw them in some soil. 5-10 days later 4 out of 4 sprouted! They grew for about 75-90 days and then I noticed a real decline in growth and vigor even with a supplied organic nutrient. I'm at a total loss... I'm taking photos today to give ya'll a look.

1 - It sounds like the soil that the onions and garlic is in doesn't have penlite in it and if it doesn't then the soil will retain alot more water and can cause that problem.
2 - Some plants will start throwing flowers no matter how old they are.
3 - Onions and garlic being fall kind of crop isn't true. We have had garlic and onions produce flowers in the early summer and have new bulbs close to the end.
4 - Some seeds benefit from being started in seedling soil also some seeds won't take long to sprout and some will. I just have seeding soil and sprinkle the seeds ontop then water them. I haven't had to cover them.

1- I planted them originally in miracle gro soil which drained pretty well; I transplanted into some sunshine mix #4, which has a lot of perlite and coco husk. I used that bag to transplant most of the garden ( all the other plants are draining/drying really well now but the garden soil before was terrible mostly clay and sand.)
3- Those bulbs from late summer; did they sprout and start to flower again that fall or did they go dormant over winter and bloom the next year? (BTW neither the garlic or the onions have been allowed to flower they are under 18/6 light.)
4- I had never heard of seedling soil but I think I might pick some up if sprouting after germination continues to be a problem. Thanks!

Could reuse the soil as long as it is pest free. Great wait to get a ton of micros.

I would bang Sarah Palin in a second if I had the opportunity. Onions and garlic and strawberries ( Oh my ) are day length sensitive.

cream pie her.
