The plants sustained absolutely no damage whatsoever.

The only negative (not much of one in my book) is the vinegar smell that lasts a few days - the product is a concentrated hydrogen peroxide stabilized with peroxyacetic acid.
Thanks, Ray. You have mentioned this product in a previous thread and noted that it may not yet be available in smaller ready to use containers for hobbyist growers such as myself. I see the "ready to spray" bottle is reasonably priced. How would I break this down to amount per quart and is it stable enough to keep a mix on hand ready to use?

The mixer nozzle on the RTS bottle is 150:1, so that would be 0.85 oz/gallon.

The do make a ready-to-use, premixed spray (that I'm trying to get), so it must be OK to store it, but I'd bet they mix it with pure water, as metal ions can cause it to decompose in solution.
