Hey Guys!
So 've just become a novice gardner! Started with growing avacado, lemons, and grapefruits in pots indoors and a kieffer pear tree outside. I recently got this dragon fruit plant online a couple of days ago. There seems to be soem weird discoloration and I am no sure as to what it may be.
I have potted it in a mix of humus, regular back yard soil (which in my neighborhood of brooklyn is very rocky and dryish) and some small stones which have been mixed together well and some stones on top. It stays in my room with the entire back being sliding glass doors. Any tips, help anything at all would be greatly appreciated. If anyone wants to see any of my other plants I'll throw them up if requested.
