Everything is different even two standing side by side. One may stay perfect and one you may have to chase the PH daily untill it levels out. That's why we have PH meters and check many times a day. Also get some proper PH down and up. Could be the reason why there. I would use battery acid instead of lime. Yes sulfuric acid is what the big comercial growers use for PH down. Very strong.
