try 2irrigations 1 feed cycle for a bit... you can gear up as it grows bigger to drink it up... otherwise you are just loading up areas of substrate where roots don't exist yet.
It looks fine. a little wobble is fine. just keep it growing vigorously. Err on the side of not adding things when you see something, especially if you try to feed a lot. nothing wrong with that, but realize you live on the upper edge and that means a problem seen is more likely a toxicity, start of one or lockout etc etc... you know which way to err when unsure at least...
