Thanks for the reps bro
I didn't notice anything being damaged from washing my plants, and my 2nd rinse was fairly hot water followed by really cold water. The blueberry gum now that it has a cure on it, has a beautiful blueberry scent and an awesome bubble gum flavor
The citric acid in the lemon juice does no harm, in fact, I have used basically the same wash in salad mixes to keep them from oxidizing from being cut with a knife. You could also use a really, really, really weak bleach water mixture. I have used this on herbs to "sanitize" the leaves for storage. As long as no one touches the herb with bare hands it lasts for months. There is bacteria on our hands that is bad for leaves, and killing everything off it with the really weak bleach or lemon juice preserves your product, by killing all the bad shit off the leaves.
