Note that if your soil is around neutral pH or on the alkaline side, you'd want to add gypsum (calcium sulfate dihydrate) rather than agricultural lime, which would make your soil more alkaline.
Good luck.

After 1 week of applying the gypsum, the newly unfolded leaf already looks darker and the unfolding leaf looks completely healthy already so it did work way sooner than I expected.
Now my largest basjoo has 4 pups and even they look like they've darkened up. Anyways thanks for the advice.
