Yellow tips?

Yeah hmmmm, greening, only a couple nutrients cause that kind of green, nornally one would blame nitrogen but it just started flowering although its presented all over olant as if its immobile but its not, the yellow tips with green moving inward tells me the plant is in control of the deficiency in that the tips die first as the plant considers the tip the least required for survival, also tells me the nutrient that is deficient is mobile, magnesium deficiencies can happen with low pH so its best to check that first and make sure it's within range. Chloryphyll has magnesium core. Grab some magnesium sulfate, drop a few spoons in a spray bottle and spray the leaves both sides, should be a overnight change in color. If it looks better apply to soil.Cook up your batch of homemade Cal-Mag supplements, using Epsom Salts (magnesium sulfate) and Calcium nitrate (a common fertilizer). The ideal ratio is two parts calcium to one part of magnesium. A safe homemade Cal-Mag concentration would be 380ppm, with 260ppm Calcium and 120ppm Magnesium. For reference, you would need around 6g of calcium nitrate and 4.5g of Epsom salts per gallon of water.
