What deficiency or problem is this?

So I have a few girls that will be outside until October. They are in a coco and perlite mix in fabric/ air pots. They have these brown spots that I have no clue what they are. I feed advanced nutrients products at a Ph of about 5.8-6.1. I had them inside under cfl lights, then gradually expose them to sunlight. Please help me out so I have a good grow and fix the problem. Thanks

Hope this helps

did you spill nutrients on a few leafs when you were watering ?

Looks like the beginning signs of leaf blight... I had it last year and it's a bitch.
