for one You don't have the right nutrients for a resin producing plant.
Hydroponic nutrients are fine in dirt I use them my self. My preference is GH 3 part so I can mix the ratio I need. It's not that expensive and found in most grow shops on line and around the net.

Second like I said the plugs are one of your big problems. If you should try dirt again...that's better then not having anything to grow. Yes dirt is slower but it still grows.

My online hydro shop is not up yet but if you need plugs I sell them 20 for 9.00 on eBay. There are none on right now only a few 36 count Aeroponics cloners but let me know and I can send you some plugs. The ones I use fit a 1-1/4" hole and are only for cloning not growing out plants. Bubblers need to have the water about 1" below the cutting and you need to have so many bubbles you can't see the bottom of the tank.
