I just checked out there site and in a lot of their bud pics it looks like they have Mag deficiencies, esspecially in the Auto-Mazar pics. The buds look incredible, but it makes me wonder about Mag deifiencies in general. Are they inevitable? Do they effect yield? I only wonder because in my hydro grow, I have been having some issues with a Mag deficiency as of recent. I figure this is because I have been running at 5.5-5.7 and Mag is not available to 5.8 (?). I have been trying to correct the problem with 6.3, but should I even worry? I know it is not pretty, but does it effect yield? i only wonder because the buds on their site look fantastic, so it makes me question my thinking.
