I have no clue as to the problem. Help needed.

Hello guys, I am having a problem with my plants and cannot for the life of me find it. Here is a pic of 2 leaves. Any help would be greatly appreciated.

I may say Calcium Def. ! This is the problem I'm having now with one baby female ! What about your pH ? Soil and Water ?

That leaf looks as though it has been grown to a good healthy state so what have you changed to cause your issue. Whatever it is, go back to what you were doing before.

Ok, well it seems to get worse when I go in to look at them. They are in veg, 20/4 light. I am in a soil less mix. I am getting so fustrated. Any help is appreciated.

did you spray anything on the leaves while under your light.. looks like a moisture burn.. most deficiencies ,or burns will show on the entire leaf not just burn spots in the middle ,usually the ends or the entire leaf,
