That's one link. What about the rest? And soil can be old. More important than age is color, consistency and drainage/aeration. I grew some of the best weed in my life when I was a spry 18 year older. I used Miracle Grow Potting Mix w/ Perlite mixed in. That was in 5 gallon buckets with river rocks at the bottom to cover the drainage holes I drilled. Gotta have drainage. Should have RO water, pH pen, take notes and wrote EVERYTHING down. Along with pictures. Make yourself a journal for your own applesauce. You GOTTA do some LST to get big yields. Lollipop em after they start flowering. It's not like growing a sunflower on grandma's garden. You need to play god and get the whole thing sorted out. You get out of it what you put into it. With good lights, good seeds and good genetics you can pull pounds out of a 4x4 tent or area. How is your temps/humidity/airflow? All critical things. I would have a regroup session, grab some Mephisto beans, get some GOOD ready to rock soil, you might even try the spice sashe that Mephisto has, or those biobizz tabs. Gotta do some research. If you really need help, ya gotta pretty much list everything you got and let the AFN guide you on what needs updating and what's fine. Be thorough and share pics for best results.
THEY'RE called KAAAAHBS Joe's dad's stuff
