I'd be inclined to bare root it and repot into an appropriate mix. I'd probably strip some of the bottom branches and plant extra deep in a fast draining soil. I'm pretty confident that even with the setback from the repot, in the long run your plant(s) will perform better than the limited potential offered by a poor mix.

It is supposed to be 5-1-1 but I clearly botched the peat measurement because it stays wet twice as long as my others and the plant is yellowing. It is visible that there is way too much peat, maybe one too many beers that evening.

Considering particle size is OK, and measurements are off, would you still recommend bare rooting? I could not plant deeper without true leaves touching medium.

P.s. all my other veggies in good 5-1-1 are thriving, thanks for the help thus far, Al.
