both of the small sugar baby watermelon i have are developing these black spots, any tips on how to manage this? i just sprayed them with calcium hoping to prevent blossom end rot, but im not sure why this happened.

all of my jasmine plants have these black spots on the leaves, then they wilt and turn brown. I don’t think i’m overwatering because the top couple inches of soil is dry. I sprayed with a copper fungicide.

Any suggestions?
