ATAMI HYDRO - Changing proportion of nutrients during flowering

Flower npk is 1-2-3. My bad typo there

----------- DETAILS ----------- Hi guys, in less than 15 days the plant should start flowering and I was taking a look at the ATAMI BCUZZ HYDRO feed chart that I have been following from the beginning and that at the moment did not cause particular problems, except for some mistakes made by myself. As you can read in the picture, A and B are always listed together and the table suggests (I think) to use the same amount. Composition of Hydro Nutrition A + B by B'cuzZ Part A: N-P-K 5-0-5 Nitrogen (N) 4.85% Phosphorus pentoxide (P2O5) 0.15% Potassium oxide (K2O) 4.73% Sodium oxide (Na2O) 0.19% Calcium oxide (CaO) 3.79% Magnesium oxide (MgO) 1.32% Sulfur trioxide (SO3) 0.11% Iron (Fe) 0.040% Boron (B) 0.001% Part B: N-P-K 0-4-6 Nitrogen (N) 0.68% Phosphorus pentoxide (P2O5) 4.07% Potassium oxide (K2O) 5.71% Sodium oxide (Na2O) 0.20% Calcium oxide (CaO) 0.25% Magnesium oxide (MgO) 0.71% Sulfur trioxide (SO3) 0.94% Manganese (Mn) 0.029% Copper (Cu) 0.001% Zinc (Zn) 0.039% Molybdenum (Mo) 0.001% Boron (B) 0.012% In your opinion, should I continue to use them according to the same quantity or is it better to reduce A during the flowering phase (contains a lot of nitrogen) and instead give B according to indications (contains Phosphorus, Potassium, Sulfur)? In your opinion how should I behave? According to what proportions? I conclude by saying that the doubt of lowering "A" came to me looking at the chart of the G.H.E. (which my friend and mentor @SwissKush is using) and the difference in aspect ratio between MICRO-GROW-BLOOM during the different phases. I'm new to cultivation and hydroponics, every day I try to understand something more and learn from mistakes. Thanks for all the support I'm getting from this community!
