Pre-bloom has begun, growth is excellent and there are a large number of new leaves, little by little I begin to prune the largest ones. Dark spots appeared on the roots, solution: added 3%-100ml hydrogen peroxide to the solution. by the end of the week the spots stopped appearing. The bush began to consume more than 2 liters of solution per day and lower the salt level, increasing it to 650 PPM. I added fasteners to the sides of the chipboard to make it possible to hang the bush. Replacing and monitoring the solution has become much more convenient.
