2 Week old seedling, stunted, deformed, and just not good at all.

The strain is Kabrales by Blimburn. The plant is just runty and deformed. I was unsure of the problem but now I have started to notice some slight yellowing of the leaves and a couple small brown spots. I think it might be a Phosphorus deficiency but it seems way to early in the plants life cycle for that to be happening. These pics were taken just today. I am feeding/watering at 1/5 strength every 2 - 3 days using General Organics. Feed, Feed, Water, repeat. PH is 5.8 -5.9. Humidity it hovering around 40%. Temps running approx 77 degrees. Medium is 50/50 coco/perlite. There is a layer of perlite on top. Plant is in a 3 gallon smart pot.

If you look at the leaves, they are small and deformed. They kind of hook under a little. Anyone know what my problem might be? I feel like the leaves should look much bigger and healthier at 2 weeks old.

So update time. Things are not improving, possibly getting worse. The plant continues to grow, albeit slowly, but the new growth is already starting to just very slightly yellow at the edges, and the older leaves are yellowing more and the brown spots have gotten just slightly worse/bigger. There is even the beginning of brown spots on the edge of the new growth.

I have been pouring over guides, webpages, and every thread on here trying to pinpoint the problem. My best guess is maybe a magnesium deficiency, but I'm hesitant to add more cal/mag to my feeding this early on in the plants life cycle. It would make sense though since I'm in coco and it traditionally has problems with cal/mag.

Also, my temps have admittedly been getting a little high. They're always normal when I check but my device shows the record high for the day and it has gotten up to 84 degrees. The edges of the leaves feel a little crispy i think. It's hard to tell when the leaves are so small and there's no other leaves for comparison. My lights are T5's and they're about 6" above the plant.

you should of planted it on a smaller 16oz cup let it established it's roots then transplant it to larger pots,,, that's how I do it....

That is an "easy button" for getting seedlings to sprout. You really don't need to do it that way unless you have limited space.
 
Did you wash you coco prior ?
I'm growing in coco and I just sprouted 3 seeds no problem.
Also I would try to raise the RH to over 50% wet towel method works well.
I try to PH at 6.0
I have 6 day old seedlings and I give cal mag every water (1teaspoon per USgallon)
Just some tips that worked for me

I rinsed the coco one time with about 2x the volume of distilled water. I have been trying to get the humidity higher. I started by putting a glass full of water in front of the fan and it has raised it about 5%. I think I'll also try the wet towel method and see how much it helps. I think I may have under estimated the amount of cal/mag I need to add. I've heard that coco has issues with cal/mag retention and it can be hard for the plant to absorb it from the coco. I was just trying to take it easy on the young plant but the combination of distilled water and coco as a medium means I need to add extra cal/mag. This is just my hypothesis at the moment.

I started feeding more frequently (every 48 hours) and giving it more liquid at each feeding. I also bumped up the cal/mag in my nute mix about 2mL.

The new growth is actually moving along better now and looks healthy. Hopefully the problem is solved but we will have to wait and see for a few more days.

Take it out of the coco perlite mix and put it into some Happy Frog. It will undergo an amazing recovery. It is not reacting well to your medium. I have had the same thing happen to me with seedlings.

While I appreciate the advice, it's just not possible at the moment. I already bought coco and I'm not going to just run and change mediums at the first sign of problems. Plus, I would then have to explain to my Fiancee why I need to buy a whole new medium lol. That's the big hurdle haha.
 
Glad that you're seeing improvement. You should have seen mine earlier this grow! They were pitiful, and now they are lush!
 
5.7-6.2 is the sweet spot for coco. Ph swings are the best way to handle coco It seems as cal/mag are not very availiable under 6.2ph.I would vary feeds if you are hand watering in the 5.7-6.2 range. Also highly recommend an ec meter for growing in soiless,since you are totally on the hook for nutrition "1/5 strength" isnt really gonna cut it.A plant that size should probably be getting .3-.4 ec..."1/5 strength" is neither accurate nor repeatable.If you dont want to bother with ph or ec,an ammended soil is a better option.

Also you CAN overwater coco,in situations with a tiny plant in 3 gallons of coco,you dont want to saturate the whole pot,you will just stunt the roots.Watering frequency needs to be high,but be careful with the volume of the feeds until you get an established root system...3 nodes or so.
