I stand corrected; I am under the impression however that fluctuations in pH also will drive Cl out of solution.
Yeah, acids will make a sodium hypochlorite solution release chlorine gas. Ammonia will do this too. Actually, this can be a problem, if someone is cleaning a nasty stale-urine-filled toilet with bleach. Urea, the main ingredient in urine, decomposes into ammonia, which can release chlorine gas from bleach.

Actually, all that talk about fluoride and chlorine probably doesn't matter for your purposes.

The tall lanky plant is probably just a sativa phenotype, not necessarily a male. You won't be able to distinguish between the sexes until the plants flower.

On the lighter white widow plant, are the lower leaves yellow? It's hard to tell in the picture, but if so, that would mean you probably have a problem.
