Thanks Weedhound. I think I was being a bit too conservative with the nutes. I am adding ppms slowly back into the res as not to shock them. they are up to 90 so I doubled in the last 24 hours. I will add more tomorrow. I put 3 drops of Superthrive into each res and will be using some diluted Colossal Bud Blast tonight as a foliar spray when the lights are off. both products I heard are awesome and I think they will like the extra nitrogen on the leaves. I did add a few drops of LK as well as 3 drops of cal-mag in the res for good measure.

Cheers
