Dosing fertilizer

[plant talk]

Please advise how to dose fertilizer as I have forgoten how much per ppm.

I have got Magnesium sulfate, Potassium nitrate and Potassium sulfate which are bought from Doctor Marick some years ago.

Have they expired?But the condition still looks good.

Please let me know how much to dose in teaspoon.

depends on the size of your tank.
NO3 - 10-20ppm
PO4 - 0.5 - 1.5ppm

Im not familiar wtih mag sulfate as i just dose 0.5ml per dose twice per week and use the FE <0.5 ppm guide.

My tank size is 2 feet by 1.5 feet by 1.5 feet, how much to dose for NO3 and PO4 in teaspoon? By the way, how do I convert ppm to teaspoon from my tank size?

I am not sure if this formulae applies to doc marlick products, would appreciate some bros who are currently using these for EI.

To target a specific phosphate increase, dose according to the following formula: 0.8vp=m, where v= volume of tank in gallons*, p=desired phosphate increase and m=volume of product to use in mL. For example to raise 20 gallons* to 0.1 mg/L phosphate you would use: 0.8*20*0.1=1.6 mL.To target a specific phosphate increase, dose according to the following formula: 0.8vp=m, where v= volume of tank in gallons*, p=desired phosphate increase and m=volume of product to use in mL.

for nitrogen, its another formulae.
