Are you having to supplement extra cal mag with yours? I see a lot of people with powerful leds are having issues with light intensity causing what looks like mag def. Is this simply because their light is too close or do they need extra mag with led as a rule?

no idea its my first run this year(i am in week 2). but last grow with fake spider i had enough cal/mag
