And hard water can cause all kinds of problems. Best to get a GOOD filter system or an RO filter. My tap water KILLS cannabis and even with testing, the cause is unknown.

thanks...maybe its not working well with the advanced nutrients ( 1st time user ) ??. wouldn`t wanna drink your water you must live on bourbon

it may have been the hps giving the impression that they are a yellow colour ,turned if off and took photo...........
