@HappyHippyBeads it looks like you may have stalled in your grow.
Couple things I noticed:
Let the soil dry out completely before watering.
When your leaves start fading to a light green/ yellow it is most often that the plant needs feed.
If not done properly you see the result.
You are addressing the mite, so nothing there.
Are these indoor of outdoor?
I need to go do yard work, so I will get back to you soon.

Hi
@Tokin Roll Appreciate the help, and yes, it sure feels like it stalled. Sour Diesel's recovered for the most part, I think she's turned the corner. They were okay until day 13.
Some more details, basically summarizing everything b/c I ramble in the journal
Soil grow
indoors. goal = move away from bottled nutes and into a combo that will allow a water-only grow.
Initial soil mix before I did the exchange to new soil = Coco fiber, aged forest materials, perlite. Low nute mix for the seedling stage.
Extra pics of in-ground outdoor *surprise* plants that are growing among the sunflowers have been added because they seem to be happy plants, and is not meant to be misleading or confusing
18 hours
light using ViparSpectra XS1000 light which replaced a cheepo depot light on day 9. Height = around 16" from the tops of the plants.
**Then** aeration = 450 cfs exhaust fan in the other section of the 4x3x6 (3x3) tent. Velcro separation panel loosely attached so air flowed through the seedling area somewhat, but it was mostly pulling through the access portholes in the flower section. Access Zipper left mostly open. I got lazy and hadn't checked temps in that section because the holding-pattern clones were happy.
**now** aeration = door completely open, fan blowing in the general direction from about 10 feet away. Did a whole re-do of the venting systems/intake systems so they're pulling cold air directly from the HVAC vent register in the room. In the flowering section, this setup gives a nice range of temps. Max = 82 during "daylight" hours, and drops down to 60 during the darkness. the open tent with the fan runs around 74. Humidity is suboptimal in the seedling tent. It's dry here, it's open & the same as the rest of the house, so maybe 40 RH.
Issues that I know I need to fix:
Mites
Fungus gnats (the sundews love the fertilizer LOL)
some weird larval something seen in the soil in one of the replacement seedlings
Soil mix optimization
General Tidiness/sanitation practices. Hard to learn since my veg/flower seedlings aren't quite as particular.
Day 11 I sprayed Azamax liberally on all the plants, using the mildest dilution rate. Brought the clones which were in a holding pattern outside to open up the area. I closed up the tents, headed off to bed and got a call from mom.
Day 12 afk.. erm, away from grow
Day 13 came home to sudden changes. Changes noted: yellowing of lowest true leaves and cotyledons. Soil changed. Very poor root formation noted during soil exchange. I did not note that the stems were hard, but looking back, it seems like they were starting to trend that way.
Day 14 revamped the cooling system. SAW mites with lens. Sprayed with a stronger dilution rate.
Day 15 holding pattern, panama red flower clones in the same tent wilted out in moderately moist soil, so went into compost pile.
Day 16 TwentyFour's green parts were wilted out. Stem hard, like a dried twig up to the cotyledons. other plants stems were noted to be stiff/hard up to cotyledons as well. Chopped off top, placed in cloner puck, then changed mind and put in rockwool in the cloner cup.
Day 17 holding pattern
Day 18 Cloner idea failed 24, tangie hanging in there.
Day 19 Sour Diesel's stem has improved, foliage improved. Still thinnish/harder than it should be, but it shed a layer of skin and fattened up. Remaining plants stems unchanged. Tangie grew a root
Day 20 Tangie's root got longer.
Day 21 will be the next post
Thanks again Tok for your help in diagnosing the issue. I appreciate it greatly.
