Three plants, same conditions, two are great, one near death?

I have three plants in my room. They all share the same environment, water schedule and amount, feed schedule and amounts- They were all three thriving until yesterday- one developed an immediate (overnight) EXTREME drooping of the leaves. I mean she looks like it's ready to keel over droop. The other two are still looking great.

They are about six weeks through veg
Left: Jack Herrer Middle: Caramel Kush Right: California Dream
The Caramel Kush is the problem (see pictures)
Environment: 85-87F, 66% humidity, CO2 is usually around 800ppm naturally. I don't have CO2 turned on, not usually until flower when the wattage is increased on the lighting.
Lights: 18x6 240W (since Jun 26) LED lights (three QB288 two QB96) about 20" from the net. Before Jun26 the QB96s were turned off, so just less wattage
Soil: this is a well-draining soil, they are each in separate pots but the soil is the same batch. I rolled my own. (never again)
Water: aged rain water, pH 6.2-6.8, usually every three days
Feed: FoxFarm Big Bloom and Grow Big.
Pests: Our house has gnats. My wife decided she wanted houseplants and now we have gnats. There are very few in my room, but I see one now and then. Nothing overbearing. Today I saw a tiny millipede or centipede in the Caramel Kush soil. A few sugar ants tend to visit the room, red wigglers and black soldier fly larvae come in with the castings, no big deal. (except the millipede/centipede?)

(June 18th) Jack and Cali began showing signs of nitrogen deficiency. Yellowing leaves that I allowed to continue too long
(Jun 26) when I remembered that Big Bloom doesn't have any nitrogen (duh). I began feeding Grow Big at full dose- for all three plants . Caramel Kush never had yellow leaves, but didn't complain about the feeding.
(Jun 29) fed again Big Bloom with Grow Big. Jack and Cali greened back up nicely. In addition new growth on all three kicked back in.
(Jul 2).Water, with some dry organic feed applied at the soil level (Esperanza tomato tone) as well as earthworm castings Still looking great. Some light LST to keep the tops under the net
(Jul 5) fed Big Bloom with Grow Big, again full dosage described as "normal feeding" on the back of the bottle. In previous runs I'd always feed half or less the recommended dosages, but since I'm not running FFOF soil and because of the nitrogen deficiency I went full dose.
(Jul 6) didn't do anything, all three plus the companion plants (marigold, lavender, clover each in their own pots getting same treatments) looking great!
(Jul7) FIVE plants looking great, but Caramel Kush severe droop. Soil feeling dry, not overly dry- normal watering would be the next day, no action taken
(Jul 7) ok so in the last third of their day I watered Caramel Kush. Mostly filled the saucer to allow it to wick upward, but watered top-down about two quarts. This is the only time I forgot to measure/adjust pH, but it's aged rainwater so usually reads 6.2
(Jul 8) At lights on everything still looks the same. Caramel did not drain the water from the saucer. I dug down a bit and there is moisture present, not overly wet.

Looking at the schedule I know I was a bit too frequent on the feeding, and I also know better than to follow the suggest dosing on the bottle- but the other two look great with the same treatment. Could this be the answer?

Please help!

I would de-pot it and see what the roots look like. Water with an enzyme. Biozyme, hygrozyme etc. I didn't see an enzyme in your regiment but I don't know all those products. Keep the top 2 inches of soil moist, with a kelp or seaweed as well. That's where I would start.

(Jul 9) No change in Caramel's condition, Jack and Cali still look great. De-potted to change soil and inspect root system. It was wet at the bottom as I'd expect after yesterday's watering, but not overly so. The roots were white, evenly spread, decent sized rootball, and not root-bound to the pot.
I replaced the soil with FoxFarm's Ocean Forest with some added perlite in a ten gallon fabric pot. Watered 1gal rain-water with 1oz liquid seaweed pH'd to 6.6. Watering is always down slowly, with a garden sprayer. Removed four LARGE fan leaves, two of which were touching the soil.

I don't have any store-bought enzymes, but I may end up brewing a batch of barley tea.

Looks pretty grim, hope it's not either of those. It's crazy how one day it looked great and with no other visible symptoms it looked like that.

Thanks for having a look.
