I thought it was a magnesium deficiency so I sprayed the leaves with a epsom salt/water combo and tonight i gave it about 24 oz of cal/mag solution. Have some pictures of the leaves and wanted to see if i was on the right track.
My hunch is lockout. I'd water with just plain water and measure the TDS of the runoff. If it's high ... a flush is recommended. Oh, and I don't recommend foliar Epsom. The potential for a thousand droplet-shaped leaf burns is real. cn
