My Cayenne pepper plant has been in relatively good health until about 1 month ago (coinciding with when I harvested its one ripe pepper and also a brief brush with aphids which were eliminated using soapy water). Since then the top leaves have fallen off and the tips appear burnt with some white spotting.
I suspected that it might be too much fertiliser (currently alternate between Seasol and power-feed weekly) so drenched it in water last week and let the soil dry out, but there has been no improvement - if anything it has gotten worse. As for the soapy water I'd say that it has all been rinsed off previously.
Can anybody comment on my problem as to whether it is a feeding or a disease problem or something else?
