    I put 90gm in 1/2 liter ro water and realized I put to much so I added a little more water( a few oz)
    then I mixed 5ml of concentrate to 1/2 lt of ro water oops I got it back asswards I should have added 95 gm not 90 and then I deluded it more
    guess it is better a little to weak than to strong and Im going to spray a few times a day after soaking in well water so no build up of salts and the vanda is only in a basket no media

    Ray,

    I have bought the MSU liquid from the vendor in Delaware. How is the label wrong?

    The labels I have seen state the formula of the as-produced powder on the label, and not the formula of what's in the bottle, which is unethical and illegal in all 50 states.

    Fertilizer labels in the US are required to give the contents as weight percent elemental N, P as P2O5, and K as K20, and all other elements as elemental percentages. If a powder is 20% of something, how can a bottle of that powder dissolved in water be labeled as 20%???

    If I'm not mistaken, the solution is intended to be used at once ounce per gallon to give 125 ppm N. For the true MSU RO formula (13-3-15-8Ca-2Mg), that would mean that a gallon of it will contain approximately one pound of powder and (I'm guessing) about 7.4 pounds of water. In that solution, the powder constitutes 1/8.4=11.9% of the total, so the actual formula should be 1.5-0.4-1.7-0.9Ca-0.2Mg.

    I suppose their labels make people think they're getting more for their money. In the gallon jug, the cost is about $0.35 per gallon of 125 ppm N solution for use on your plants. If you bought the powder, the cost for that same final solution would be more like $0.05, not to mention not having to pay to ship water!
