Last summer I bought a Monrovia shrimp plant (justicia brandegeana).

Patty, turn the leaves over and inspect the underside carefully for signs of
infestation. I'm going to guess whitefly or aphics. High N can do it, too,
as can some viral infections.

I checked it for bugs when this first happened, but never found
anything. I'll get out a magnifying glass, but there's certainly
no visible infestation.

I assume that, unlike salts, nitrogen would not be washed away with
deep watering, so I would deal with that with the proper food?


Monrovia is the name of a giant nursery company... not part of the plant's
name, fwiw.

?? I didn't say it was part of the name. I was indicating who
had bred the plant, in case people wanted to know whether it
was from a reputable source.
