Q.My Night Bloom Cereus Has Strange Spots On The Leaves I Just Emptied The Dish Underneath The Pot Which Had Collected A Lot Of Wate
r. I can’t tell if an insect did this or if its from too much water or something else. I have not had this problem before so I really hope I have not killed it! It has been outdoors in part sun/shade through this summer’s drought and recent cloudbursts! Thank you for any suggestions!

This looks like bacterial spot. It doesn't look bad, yet, and looks to be easily treated with a fungicide. Do be sure that the soil has time to dry out, thoroughly, between waterings. These plants can handle drought, pretty well. They cannot handle overwatering.
