So overwatering afected all girls except SHERBET who stayed strong
I thought what apeared on the leaves might have been ROYA / RUST or ALTERNARIA.
Having no dedicated remedy for this y added a couple of drops of bee propoleum, stopped watering and transplanted to 7L pot.
NL is another one that dint grow as much is expected....
will cut of that leave that still shows those litle brown spots.
