Hi all. I know I've been away for a while but I had to seek help with this sickness that has attacked and keeps on attacking my phals. Any advise would be appreciated as I have tried many things but nothing seems to help.

PS the third picture is of the second leaf on the plant that was attacked after I'd removed the first infested leaf.

PPS the infected area starts with a discoloration, then an indentation and then browning.
