Coco growers! How do you dilute your nutrients?

[SeymourGreen]

I thought the same thing with the cal/mag water. I figured it would throw the ratios off. My last run from seed of the Darling Nikki, I did not dilute with the cal/mag water, just tap. I figured I did not want to add the extra N in flowering. That run was super easy with no issues. Now this run of the same plant, but from clone, I started doing the same thing. Just diluted with tap. I started having issues almost instantly, so I started diluting with the cal/mag water again. Not sure if the tap had anything to do with it, or if it was lock out from salt build up, or the coco releasing K, but something sure got screwed up. Thinking of going back to Ro, so I have total control of what’s in my water.
