Sorry been away Priss.....How old are the leaves...is it all of them or just
one or two....what kind of leaves just lilies or all plants....... What have
you added to the water or plants.... With all the rain could it be washing in
from the surrounding area I will check the answers tonight or tomorrow....bugs
will not turn the edges brown....sounds like some type of burn. Aphids suck
juices and the evidence that shows up from them is paleness or streaking. By
the way aphids come in many different colors. Jerri
