Its universal, how many plants it will do will depend on how many total liters/gallons you mix. Meaning in the beginning 1 gallon will feed several small plants, but in 2 months you would need 10 gallons to feed the same amount. I am assuming you have a ph meter already but make sure you pick up an EC or PPM meter, it's a must using chemical nutes. And take it very easy with the nutes at their first feed. You dont want the total feed ppms over 600 or ec over 1.2. They(plants) will slowly tell you when to increase the strength as they grow.
