With an 18% Nitrogen fertilizer you're going to end up with alot of leaves in the bud. I would try to find an alternative potting mix. If that's not possible, cut out any Nitrogen nutes. I'm not familiar with the Botanicare line but I looked it up and there seems to be three different lines with formulations for Hydro and Soil. Let me know which you are running and I'll try to help.
