I'm thoroughly novice! I need help!!
She's 13days old. I think it's SMALL, CUPPING, DROOPING, YELLOWING (Also she has Purple Stem and Yellow Cotyledon, But that's okay...right?)
She started to Cupping Around 6days. And now she's DROOPING and YELLOWING tip a little.

・C99 Auto (13Days old now)
・Grow tent size 3feet×3feet×5.2feet
・LED light 8000lm 150watt
・Cheap coco soil and husk 4gallon, Perlite 1.5gallon.
・COCO pH6~7,WATER pH5~6 (I'm using citric acid for pH down, Bad for her?)
Rh55~65% ( I spray it to wall and floor inside the tent)
Temperature 78.8~84.5 (Basically it's 80.6)
Co2 400~1800 ( I shut the window for 12hours while I'm outside)
18/6 Light schedule

5/17 15:00 Soak in ph6 Water
5/18 15:00 Sprouted, Put into COCO
5/19 Spray
5/20 Spray
〜Week1〜
5/21 Got up and show her leaves
5/22 Watering 0.5oz pH5
5/23
5/24 Watering 0.5oz pH6
5/25 Watering 0.5oz pH5
5/26 Watering 1oz pH5 (Started to Cupping, I thought It was a Heat stress. Because COCO surface was dry like Light Brown and Inside was Dark Brown, But it was not wet I poked my finger)
5/27
〜Week2〜
5/28 Watering 1.5oz pH5
5/29
5/30 Watering 1.5oz pH5 + 1/8 Fertilizer
5/31
6/1
6/2 SHOULD I WAIT?? Or give her a Water? With Fertilizer?
6/3

・Cupping
When she was started to Cupping, I set the Light 25 ininches to 35 inches. She's gotten better, But STILL CUPPING...Temperture?

・Drooping
I think it's Overwatering. But I quited watering for two days and COCO dried, Nevertheless leaves getting DROOP FURTHER! This means, I should wait few days more? Or It was not because of Overwatering?

・Yellowing
It started with Cotyledon, And then leaf's tip, And gradually all turns to yellow. In the end, Tip gets Brown and quit growing. This become routine. Now cotyledon gets yellow and leaves droopy again...

I'm using Paper tester so I can't tell the exact pH. It's like 1.2.3.4.5........14. And I don't have EC meters. Too expensive to me...
I got two more seeds, Any advice for next time? Where did you guys learned from? I know growweedeasy.com tho
It's bad for root to be exposed to the light, I'll fix it, Thanks!

I took First two Pictures today, The last one(The close one) was Day8.

I had the same cupping trouble with a Pineapple Express seedling recently. It was in soil and drowned to death. I get yours is in a different medium though. I personally don't have much co-co know-how. I am curious though - did your seedling survive?
