Most use the feeding schedule prescribed by the nutrient company, or some modification of it. You can also search for the Lucas Formula or method.

The AMOUNT of liquid makes no difference;
I just use a ppm meter and dont measure EC


Seedlings, Early Sprouts 100 to 250

Early Vegging 300 to 400

Full Vegetation 450 to 700

Early Blooming 750 to 950

Full Mature Blooms 1000 to 1600

Final Flowering 750-900

Note: EC Calculations are different, here's a conversion chart :
heres a great chart that shows how different PPM can be from meter to meter... EC is the only real universal language...



Remember to subtract the ppm of your water.

Also, make sure that you watch your plant so see if you are too strong or too weak..
