White spots? not spider mites or mildew help?!

I'm in my first week of vegging with clones. Fox farm ocean forest soil. Recently watered with dolomite lime, (thinking it's a ph imbalance?) I recently started to get white spots on my fan leaves. Not my new growth. Is this a calcium deficiency? I check with 30x magnifier and it isn't spider mites or mildew. Any help would be very greatly appreciated! how do i add a picture? it show an [ ! ] after i load. Thank you
