ninja-you flush with the micro? I've never heard of that, what does it do for the plants?
yup, generally a weaker head solution, so generally around 2-3ml.
what does it do per se? no idea lol. I just figure a weak solution would make more sense then straight water, so it still supplies the micro nutrients for that day or two they are being flushed.
notice more on younger plants, after a good flush, they tend to "lighten" a bit, using the micro, they stay nice and dark green.
