I am having a terrible time getting my autoflower seedlings to grow. I started 4 of the seeds in plugs and transferred them to a 3 gallon hempy tub once they sprouted up. However, they immediately showed signs of overwatering (really bad downward curling/rams horn), so I transferred those seedlings to individual 16 oz cups. They still haven't shown any recovery from their curling problem. Also, I stupidly gave them a really low dose of FF Grow Big (1/8 tsp/gal), but realized my mistake and flushed with tap water the next day. I haven't used any nutes since. What really confuses me then is that the seedlings are now beginning to turn really yellow, even though I haven't given them nutes for 2 weeks and have flushed multiple times since.
In addition to the 4 seedlings that have been tortured by my terrible gardening, I have 3 that I started about a week later. These have never been given any nutes. But they are showing the same stalled growth as my other plants.
Also, it's probably important to note that I'm growing under 126w LED. If any of you can take any guesses at what my problem might be, I would really appreciate it.
How long has this problem been going on? around 2-3 weeks

What substrate/medium are you using?(Hydroton, RockWool etc.) Perlite
What is the Water temperature? ~60 F
What color are your roots? White? Brown? Are your roots slimy? White
What Nutrient's are you using?(If growing soiless) I used Fox Farms Grow Big on the older seedlings at a really low dose (1/8 tsp/gal), but switched back to tap water only
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*
How often are you feeding? (If using soiless) Watering every 2 days or so
How often are you giving nutrients? (If using soiless)
If flowering, when did you switch over to using Bloom nutrients?
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
What is the TDS/EC/PPM you are using?
What is the pH of the "Tank"? Water has a pH of 6.0-6.4
Are you sure your calibration is correct on your equiptment?
When was your last watering? Yesterday
What is your water temps? ~60 F
When was your last feeding change? (ie. grow-bloom-micro-additional)

What is the canopy temperature? Usually mid-70s, but sometimes as low as 65, lights on
What is the Day/Night Temp? (Include flucutaion range) Same as day usually since lights are 24/7
What is the current Air Flow? (cfm etc.) Good enough
Tell us about your ventilation, intake exhaust and when its running and not running ? 2x 120mm fans running constantly
Is the fan blowing directly at plants? No
Is your water HARD or SOFT?
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? I have been using tap water, but recently switched to distilled to see if that improves anything.
Are you using water from a water softener? No
Has plant been recently pruned, cloned off of or pinched
Have any pest chemicals been used? If so, What and When? No
Are plant's infected with pest's? No
Here are some pictures. First pic is one of the older, more stressed seedlings. Second is one of the younger, greener but still stalled seedlings. Third pic is of all the plants as a reference to their size.
