Brown spots on leaves-20 days flowering-pics

Hey guys my plant is an oaksterdam OG clone, and she is about 20 days into flowering now. I just noticed these brown spots on the leaves, and a few of the leaf tips curled upwards. I just recently fed her bloom booster nutes at about half strength. It was only the second time I have given her nutes in flowering. The first time I probably gave her about 1/4 strength dose of nutes. I also sprayed an organic fungicide on her called Organicide a few times spread out about a week or so between sprayings because earlier in veg I am pretty sure she had some powdery mildew. I did spray in the dark. Anyways, any help would be appreciated, thanks guys!!! Ohh ya, and I put about a tbsp of epsom salt in there last night. Sorry one last thing, I was watering her only about once a week in veg and so far have been doing about the same, because when i stick my fingers in its pretty dry up top but like 3" or lower and its still a little damp so I figured I shouldn't over water her! I don't know if i am rambling on now, but I thought I should give as much info as possible.
 
Have a similar problem, I think it's hardwater.. Maybe to much calcium in the water? Trying flora bloom w/ hardwater micro. Just a guess??
