On my flowerless Phal I have 2 large healthy leaves and another one
appeared recently. Since we are having heat wave here in the east, I put
them out on my patio where it gets all the humidity that this heat wave
brings and maybe 15 minutes of morning sun, the rest is in shaded part
of patio. This morning i noticed on one of the larger leaves a blotch
and another on the other leaf. What gives?
