SMany times fertilizer solutions from crystaline fertilizers are too acidic and must have "pH Up" chemicals added to them, especially if they are being used for container plants in areas where the tap water is not hard enough.

This wouldn't cause BER, though, surely TZ?

Thanks for the input, dice.
