the roots never developed, they remained more or less the same as when they were transplanted. the place is a 3m wide terrace facing east with a wall of several meters on the west side so in summer it was completely in the shade for most of the year due to the fruit trees planted very close. probably the microbial community has been modified but I did fertigation with seaweed and microbes and 4 foliar with seaweed microbes molasses magnesium sulfate, calcium, silicon, iron, manganese, molybdenum, boron and nitrogen in the form of amino acids to chelate the minerals but the brix never changed. could it be nitrogen deficiency? The compost is bad quality probably partly made up of pine branches, but if it is a compost problem or water quality or something that is the same for all plants shouldn’t it affect all plants?
