Soo hard to tell but it looks like a magnesium deficiency or iron but that's more rare. The leaf of the right with a more pinpointed spotting it look like thrips. Without knowing what you're feeding her, what the ph is etc, it's hard to tell. If she was mine first and foremost I'd test ph. Most issues occur when the ph is off, it can lock out the plants ability to take up nutes properly. Doesn't hurt anything to spray her with neem to rule out mites, insects and fungi. But I think it's a micronutrient issue probably brought on by the pH balance. Hell it almost looks like it could be light burn possibly. I'd need alot more details to help narrow it down.
