ACK!! Is this calcium def? Or something more sinister?

Ok. I've looked online for awhile now and I think I may have a calcium def. My ph is SOMEWHERE between 6. and 7. (crappy tester). So I don't really think I have a lock out. Whatever it is I DO need help. I know it probably won't affect her too much, but I want her to be the best she can.

those look like burn spots, i have those spots with my Hogsbreath clone. it was too close to the 2x 65W 2700k CFLs i had. Ever since I changed those 2 bulbs out and now are using 4x 23w 2700k CFLs. Less heat and no more burn spots. Is your plant maybe too close to the 2700k lights you have? I have a expensive Ph tester too ($60) and my Ph level is at 7.

Well I've looked at all the pics I can, and it seems like a calcium deficiency to me. I was just hoping someone could confirm before I start throwing dolomite lime on it. I use distilled water and haven't seen any mites. And as to hotspots, I actually had foil under it until the last few days and this started after I pulled t. So while I won't rule it out, it's one of the last things on my list. So idk. I need to put her into flowering soon, i just can't bring myself to do it when she's in stress.

I have the same issue and I am confident it is cal def. I use RO water, which also has no calcium, like distilled. I am using fox farm nutes, which also have no calcium so today I bought some botanicare cal mag. 2 tsps per gallon added to your fertilizer should help. I just added it to my setup today and will keep you posted on status.
