The first week of flowering has passed, the plants began to stretch and eat a lot up to 850 PPM
I changed the light to a custom one, put the spectrum in the photo, in my country they praise it very much and many reports with it were carried out with decent results in terms of the mass of cones. If there is not enough light for blooming, you can always add Mars Hydro SP-250. We are looking at the further development of the plant.
The problem turned out to be the following, a large amount of fertilizers in the recommendations from the Planters 700 ppm
I washed 400 PPM with compote at the outlet from the drainage, we have 450 PPM. A day has passed after washing, the flowers begin to recover after an overdose.
The conclusion is the following for the first weeks of growth in salt content, fertilizers in the solution, 400 PPM should not be added
