Longtime no see @baldmountain. I would let it dry out first. Once it is dry I would transplant it. Knock off the old soil and transplant it into fresh soil. Water it bottle water or rain. Good luck.
I'm seeing multiple nutrient deficiencies, which tells me it's time to flush your root zone with a fresh batch of nutrient solution. The flush is to displace any possible nutrient excess concentration there may be and replace it with fresh balanced nutrition.
