Elite 91 - FLOWERS - Professional Bloom Additive – 500 ml

A Professional Bloom Additive Built on Phosphite Most bloom additives deliver phosphorus as phosphate. Elite 91 FLOWERS uses phosphite instead, which is a smaller and more mobile molecule. Roots and leaves take it up more readily than they take up phosphate. The formula carries phosphates, phosphites, potassium and nitrogen together. Rates climb through the cycle rather than staying flat. Elite 91 call for 0.5 to 1 mL per gallon in the last week or two of veg. Early bloom moves to 1 to 2 mL per gallon across weeks one to three. Mid and late bloom sit at 3 to 4 mL per gallon through weeks four to eight. An aggressive late push of 6 to 8 mL per gallon is listed, with a caution attached. Use it at every feed or reservoir change through that window. What Phosphite Technology Changes in the Reservoir Phosphite is not a straight substitute for phosphate as a nutrient source. Plants cannot use it the same way, so it works alongside a base feed rather than replacing the phosphorus in one. That is why the rates are small and why the product is called an additive. It runs in soil, coco and hydroponics without a change in method. Keep an eye on total EC when you stack additives, because small volumes still add salts. The aggressive rate exists for a reason, but the caution attached to it exists for a better one. Start at the low end of each window and move up only if the crop is asking for it. Five sizes are listed, from a 250 ml bottle to a 20 litre drum. Pick the size against a season, not against a single run.
