Alright, as the title suggests, the water where i live has a great deal of calcium carbonate (a salt). I'm a noob and assumed this wouldn't be a problem. Well it is. The lower leaves are curling up and are slowly browning and dying. Is this a N, P, or K deficieny and how do i solve it. Obviously from now on i'll just use distilled water, but my plants are dying and i need a solution...FAST!! Many thanks in advance, please save my babies!!!!!!!!!
