cryptocoryne,Cabomba and Nymphaea

How long have you had the plants? The last 2 changes especially just sound like they're transitioning from emersed to submersed and/or to new water parameters.

You also need to learn to be more patient... Posting a clickbait-y post with the link to another post, **17** minutes after making the first, let alone when it's early, early, early morning in the United States (where most of the site's members live afaict) is not a good way to get people to like you around here (or anywhere really). You don't need attention that fast for a problem that 1. isn't life or death 2. doesn't need immediate action and 3. can't be solved in a second.

I've seen people with actively dying fish that don't demand that kind of attention, and by making a second post just to draw attention to your first, not even half an hour after you made it, you're clogging the recent posts and taking attention away from people who really need immediate help. Please learn to understand that you are not the only person who needs help and that problems exclusively with plants are pretty much never ever ones that demand immediate attention.
