My Secret Methods !

I use a common "dial-a-spray" injector to foliar feed my gardens.

I will foliar feed with just 30 ml of a liquid (Any of the Advanced Nutrients ones I use) in one litre of water filling the dial-a-spray.

I set it to inject at 60ml per litre, and spray away, usually with no higher than 1200 mS/cm EC watering the crop.

I have hard water here, about 350 mS/cm from the tap, so about 900 mS/cm is from the fertilizers I use like Advanced Nutrients' Micro, Bloom or Grow.

Colossal Bud Blast has no (or very little) EC, B52 might have an EC of 550 when applied this way.
