Why are the leaves of my Peperomia plant curling and have dark spots on some of their back sides?

These guys like to dry out. My first guess would be a watering issue. If you are confident your watering/fertilizing is not the problem, then I would suggest it could be a Calcium/Magnesium deficiency (if you are noticing the new growth coming in deformed and weird).

Mine did this and all the research I found lead to that. These guys need more Cal/Mag and there isn’t enough in most regular fertilizers.  
I found it on amazon. So far I’ve used it 1x and the leaf shape has improved.

As for the brown spots on the back….those haven’t changed on mine.

I have a caladium with curling leaves and weird growths, can you screenshot which cal/mag you use?

Got it on amazon. There are a whole bunch of options though. I only picked this one for the price/size (I ordered the smallest bottle).
