Not to highjack this thread but I wonder if this is considered the "drawstring" you speak of? Mine is a Bianca and has lots of red new stems but I figured it was just the strain. I only see about 3 leaves total like this.

That is the effect. The drawstring is actually caused by calcium deficiency, which usually precedes mag deficiency. Calcium is an immobile element and cannot be borrowed from the lower leaves. You see calcium deficiency in the newer growth. It drawstrings, then can actually turn the leaf upside down. Magnesium is a mobile element. When the new growth needs it, the plant will take it from the lower leaves. When I see a drawstring starting on my newer growth, I generally treat with cal mag because the magnesium deficiency is close behind.
But......But I also agree with AK. Your medium may have adequate amounts of everything and you still get an abnormality. This particular leaf may slept in on the day the calcium was handed out, or may have been acted on by something completely unrelated. You also need to consider the overall look and health of the plant. You have much newer growth on the plant that is perfectly straight, so whatever hooked this particular leaf was not a problem beyond it.

I attached a couple of pages. These are scanned so hopefully they are clear.
