I actually gave her to my Gf to care for but I don't think it's ever had cal mag and as for fertilizer I don't think much. She says maybe once a week - not sure. It started as just one or 2 leaves but now it's much worse. The fertilizer is Fox Farm grow big. That plant was stressed pretty good as I put her outside in what could be called a Nor-Easter. Windy and rainy and cold for days. It had a bad case of spider mites, She kept washing the leaves and it worked. I've never had a plant have curled leaves like she does. This was one of the first leaves - weird.
I don't know.
