white blotches on my girls leaves..

These spots showed up a few days ago on number of my plants and I'm not sure what it is. I couldn't find anything really like it in any other posts. And then the two bottom leaves in the other picture just started turning yellow and dying but the rest of the plant looks fine. I think it may be a lack of phosphorus? Any advice is much appreciated.

First pic looks just like a clipped leaf off of a clone thats kicked the bucket... Second Pic not sure bud.. Looks like some bleach rolled down towards the stem (j/k).. First looks fine second i have no idea
