Got myself a little john bottlebrush a few months ago and potted it up being wary that they don't like a lot of root disturbance, i put it in a mix of 60% amgrow black label bonsai mix and 40% 4mm minus diomite. I gave it a seasol bath at potting and a week later, I have been vigilant with my watering making sure it doesn't dry up but trying not to get it too wet, it has now been a month since potting and all the foliage is drying out and slowly curling. Is this tree lost or is it salvagable?
I really hope i can save this tree because it's my first native and it's pretty damn cool looking

Any advice would be greatly appreciated, I will post pics if this helps too, just unable atm.
Thanks, Mitch
Edit: also, i have kept it in mostly shade since potting and have tried my best to keep it wind protected.
