As I recall, "Barrs GH Booster" contains a lot of potassium sulfate, so I doubt this being a potassium deficiency. We need to start at the beginning - the lighting. What specific light fixture are you using?

I vaguely recall that Anacharis is a cool water plant, which doesn't handle warm water very well. If that is correct, is your water warmer than it used to be?
