Whats my deficiency?

[JackBlasto]

Crypt balansae are all crinkled. Mostly older growth but I'm wondering what causes this and know someone on here will know. Any advice? Thank you.

Are you talking about the twisted leaves or the actually crinkling on the leaves? Balanese leaves should be crinkled but not twisted. Twisted leaves can be from an overdose of magnesium or potassium. It can also indicate a calcium deficiency.

Yeah, I meant the twisting... I've read so much that says too much potassium never hurt anything but I've also read what you just said. For some reason my potassium tests high in that aquarium regardless of what I do so I'm guessing that it can in fact cause a calcium uptake problem and hence what you see here. Anyway, thanks for the input.
