Knoweledge is good. I usually add supplements to the soil in addition to the Fox Farms products. I did not know that there is no nitrogen in Ocean Forest. I guess the guano and worm castings should have a good amount of nitrogen and should be a good supplement. I have never tested my soil. I just try to keep using organic products like compost tea and worm juice for fertilizer. I figure if the soil is alive and healthy it should be good enough. Information is always welcome. What do you find when you test the soil. Just the ph. Is there something more like the nitrogen level. Do you ever test for moisture content.
