Ehm...Dazed, with all due respect, I beg to differ.
Purpleish reddish stems can be an indicator of temps being too low, certain nutrient deficiencies, or it could just be in the genetics, that this plant gets red stems. But I assure you, that purple/red stems are, generally speaking, normal...ask google, lol
Now.
As for you, Mr. A&W Rootbeer.
Pictures 1, 4 & 5.
Im assuming these are cut off bottoms from 2L bottles, no?
If yes, that's a good thing.
You won't have to transplant them, per se, once they get this 'root ball' you're waiting for.
I've never done it, but I know people have, is start their plants in like....red party cups (solo cups) and then when its big enough, they will dig a hole in their new pots soil (or in your case coco) and then cut the bottom off the solo cup and then plant the whole she-bang .... but again. I've never done it, so I don't know any more about it then what I just said lol. So you can, in theory, do that with the soda bottles. I would assume you just take a box cutter or a pocket knife or something, and ever so gingerly, lol, cut away the bottom half and plop it into its new home lol.
Really though, the plants look healthy-ish to me.
Stunted though, definitely.
This is one from my latest run and she's 6 days old.

so we've got the same amount of leaves (4) but these are much larger.
why?
Well. if we didn't already know you were having problems, id chalk it up to genetics.
But since we know you're having issues.....hmph. tis the hard part....for me anyways, haha.
Because youre obviously stunted. Your plants aren't showing 2 weeks of growth. This is another one of my plants (from my 2nd grow) at 2 weeks -

My next guess is the same as Dazed, and that is pH.
It's kind of ridiculous how important the pH is....and I didnt realize it at first either, so don't feel bad lol
but if your pH isn't in check, you will definitely run into all sorts of problems....stunting them being one of the problems that can arise...in addition to numerous nutrients being locked out...meaning, even if the nutrients are there and available for the plant to use, if the pH is off, the plant cant utilize them.
So perrrrrrrrrrsonally, lol -and take everything I say with a grain of salt, because Im not a great grower lol, but personally, I wanna say either your pH is fucked up because you put lemon juice (
which has a pH of 2 btw) in the water, bringing the pH way down, in turn bringing the pH of the coco way down OR your you didn't use enough lemon juice in the water (which btw you dont want to use straight from the tap, you wanna let it sit out for at least 24 hours to let all the shit evaporate off it lol) and the pH was still too high, making the pH too alkaline, in turn doing the same thing to the coco.

I'm super high, so this took wayyyyyy longer than expected and I'm sure someone has already said all of this lol
