botanicare question

Hey guys im running a rdwc system this is my first but second grow I have my first grow in dwc buckets but anyways I was going to ask is botanicare pure blend pro grow or bloom or should i switch to cns17 for my rdwc and when I do the nutes every week do I flush every week or do I just add the nutes thanks guys im doing my grows all under cfls and they look great

Can anyone help?

Flush every other week. I know its different brand, but I use sledgehammer for one watering every other sunday. Also, I would stay with the nute line you currently are using. I've used both lines from botanicare for my ebb and flood system and don't see much of a difference. From what I understand the cns17 was designed with hydroponics directly in mind. Hope this helps.
