I see that, and now remember why I stopped using that years ago. Really it sounds like you were already to get into mixing up your ferts from salts, why not just go ahead and do Jacks Hydro 321? I have never looked back. Damn I am starting to sound like a Peters sales rep. you can look up some of my post in the last few days (have been home sick LOL). You can also hit the Nutrient sub-forum, some huge years long threads there. If you can't find an answer just post here or ping me.
