Very slowly it is coming around. I have been giving very small amounts of water with high concentrations of acidic nutes/additives. I shall outline, and the process is still ongoing.

Once it was clear we were too alkaline and too wet, we cleared the new potting soil off the top of the root ball and gave a liter of water with molasses pH'd to 5.0. This resulted in the tops reaching to the lights again and improved green color.
Next day I gave PhosphoLoad, pH'd to 5.5 in the same manner in a liter of water. Maybe greener next day but not as reaching to the light.
Day next, I gave cal/mag pH'd to 5.0. (note this is almost exactly the same as giving molasses) 2 ml in a liter and poured around the outside on the new potting mix. Much greener 2 days later when I returned from out of town and reaching for the light again. So a day without water was in the middle.
Day next I gave 2 cups of water pH'd to 4 with distilled white vinegar. Will see results soon. Went and bought pH Down as I do not want to continue to give a bunch of salts.

Overall the plant is looking better, still have the clawing, but no new clawing.

The topping is so impressive I will try and not space out a pic today to show the huge difference.
