I can't directly give you all the information on everything I know. I CAN tell you that there's a lot of information on this site and other sites.

Nutes? I recommend Organic, whether you do a tea or organ nutes.

What to use to increase grow? Not sure if you're asking me what to use to increase the size of your grow or your yield. Make sure your canopy is fully utilized. Make sure they're in a good atmosphere. If you need to expand, use something bigger than a tent.

Yield more potent? Hmmm... You gotta give it your love, care and affection man. Cultivating is a two way relationship; she tends to pay back in the end for all that work.
