I believe one of my Sikkimensis, had Calcium and Boron Deficiency, The leaves were emerging with dead tips, thickened veins, and smaller. I ground up some drywall gypsum, and made a liquid solution to water with. Then I took some boric acid roach killer, about 1 gram to one gallon, in a sprayer and spray every other day. The new leaf is emerging much better. Kind of strange since my yard is full of limestone, and chalk?

If I recall correctly, calcium and boron are antagonists. If one is high, the plant has a hard time taking up the other. Given your comments, I wonder if it isn't a boron deficiency caused in part by high calcium in your soil. Another possibility is that soil pH is out of whack, which can make it difficult for the plants to take up certain micronutrients.

Might be PH, going to have the soil tested in a couple of days. The new leaf is perfectly normal since the calcium, and boron applications, so something is messed up. Good to know you can use gypsum, and boric acid lol
