he breeder gives between 8 and 10 and may be 10 as I watch. Max 11. Since over 50% of the leaves are damaged (by deficits) it seems to me that it does not photosynthesize properly. At least that's how it seems to me.
I already water with Bloombastic 2ml / L, BioHaeven 10ml / l and TopMax 8ml / l all this in 2 l of water. pH 6.4, EC 1.2, which seems low to me and quite a lot. In principle, it should be between 2 and 3.2 for this stage of development, but I do not know how to lift it so as not to stress the flowers with more fertilizer. Only Bloombastica has macronutrients like P and K at 20 and 20. There is almost nothing in Haven and Topmax.
