Fertiliser calculation.

[bil]

I am trying switching to making up a solution instead of measuring out the dose dry every time.

My rains are fried with a bad cold, so can someone just check the math?

The container holds 300 mls and the logical liquid does is 3 mls, so the jar will need 120g, ie 100 x 1.2

So the way to make a solution of 300 mls is to put 300 mls into the jar, and mark the level.

Then emmpty the jar, put in the 120g and fill the jar to the 300ml mark, then each 3 ml does will contain 1.2g

Wih a cold like this I coud so easily see the decimal point being aywhere.
