Sick leaf any ideas?

[Masi808]

I found one of my girls looking a little yellow and a few leaves with these spots know i know i got some nute burn and need cal mag but have no clue about the spotting

I believe its calcium or mag def.i recently had this problem.. more likely ur ph is off at the roots causing some kinda lockout.. thats what mine was.. or u may just need to add calmag
