The burned leaves (that is the best way I can describe it) rapidly fell off the plant until I was left with just over half of my original leaves. The plant growing in the small pot of soil flowered in the meantime. I have just taken cuttings of all the stems growing in semi-hydro to re-root and grow in soil. I just have to surmise that the plant just did not like growing in s-h. I will hopefully be successful and be able to bring this plant back soon.
