Hey, Nugbong good first outdoor grow can I make an observation I saw in a few of the pic’s pine or cedar trees, this might help explain your low yield and some of you growth and disease problems . The soil under and around can range from a little acidic to very acidic. This can stunt or otherwise slow growth. I had been growing outdoors for more than 20 years. I have made this mistake before; invest in a probe outdoor garden ph meter. I check all areas that I grow in. The ph can change a lot with in just a few feet. Also if the place you want to grow is acidic you can treat the area and the surrounding area with lime cheap and easy. Just an observation, I made the same mistake twice before I figured it out. Couldn’t figure out why clones from the same mother with similar amounts of sun and the same nute’s and water could grow so different. Good luck and good grow this year.
