This is one of my Sikkimensis after one dose of gypsum water, nothing else was changed, note the older leaves are all the same size (slight twisting to the one on the right, another calcium hint), then abruptly the new leaf is much larger, also notice the red midrib where the other leaves have none, the bottom of the leaf is now bright red also. The soil is full of limestone that should provide calcium, but it is all not bio available to the plants because of the acidity. The result was stunting, and deformed foliage, lack of color. While most areas, and cases wont be this extreme, PH can matter.
