I have this phal bellina that's currently blooming, just not sure why there are these patches on the leaves, anyone can ID?
I think the last photo is sunburn, though not very sure, it's an indent that's just like that, but I'm worried about the other area though, I thought it was red spider mite attack (those pests seem to have found their way to my garden lately) but there's no sign of them... anyone can diagnose the problem?
