I looked at the fertilizers you use. and I'm surprised. why don't you use Floragro? it is the main component for the growing season. florabloom and floramicro also contain nitrogen for growth, but its highest concentration is in floragrow. I strongly advise you to add this component. so does Fulwick. you can see my diary. I actively use fertilizer from general hydroponics. at this stage of growth you need to give the next dose. floragrow 1.8mg per litre. Floramicro 1.6 ml per liter and florablum 0.5 ml per liter. Fulvic 2 ml per lit. + salcium and magnesium.
