These plants are starting to develop flowers, but the leaves seem to be curling up at the ends, drying up and dying. I've attached a few pics. Is this a PH level problem or what? Thanks.
What did you add to the water to bring it so low??? it should be 6.5ph, that is way to acidic for the plant. I see some nute burn perhaps the nutrients your adding to the water is sending it way down like that.. Suggest you flush your plant with distrilled water which has a neutral Ph of 7.0 to flush out the salts in the soil.
oh to answer your question, simply goto a walmart or kmart or pet shop and find ph up and ph down for aquariums.
