leaf tips hooking/circling....wtf

Hi all,

I have a really strange problem. I have a bubba kush from dr greenthumb that the leaf tips are hooking sideways. I can't show pics sorry. It's not all the leaves but it seems to some of the new growth. It's like a little sideways hook right at leaf tip. Leaves seem normal otherwise. Anyone have any ideas what this could be?

I can't be sure but when I had this issue (along with a few other symptoms) I deduced a Mg deficiency. A foilar application of some epsom salts and a healthy watering of the same and it seemed to correct it. It seemed to be a reccuring issue but when I noticed it or other symptoms the treatment seems to correct it quickly (a couple of days). Honestly, my plant seems to be a MG whore, she loves the stuff. I have since worked in an epsom salt feeding into a regular feeding regime (one treatment every 6th-7th watering) and have not noticed the problem again.

come on.........pics and juicy details.
