My water hyacinth is looking really sick; leaves are turning brown,
plants are definitely in trouble. Ph is perfect, what could the problem
be?
Anarchis also does not look good. My marginal plants are doing great,
water
lilies are phenomenal. Your advice would be appreciated.

When mine get like this, I dose with Potash. I use one fat tablespoon per
1000 gallons.
