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?

Actually, most of the N salts are quite soluble. But without knowledge
of your soil analysis and fertilizer use, and how you've treated it
since it came from the nursery, I threw that out as a possibility.

Still, you might consider rooting a cutting, growing it in plain sand with a
low N fertilizer, and seeing if that straightens new growth.


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.

My misunderstanding. Since the capitalization and spelling of the binomial was
wrong, I didn't know if you knew it was a nursery as opposed to part
of the common name.
