Autos they are blooming from about 10 - 14 days now, few lower leaves yellowing with couples of black spots
soil Ph is 7 i water them with ph downed water of ph 6
cut that silly leaf off already, geesh. its not photosynthesizing anymore, your plant is embarrased it sticks around.
ever see the color of sticky pest strip....
lower leaves are shed often as a plant matures, less light, less love no worries
