hey! i just got my first ppm meter, need knowledge.

so how is this supposed to work? and how much is to much ppm for a plant thats 3-4 weeks into flower?

with the cutting edge nutrients? and bud candy.y

I hope it was a bluelab! you need much more details if you want a answer.

never over 1000 ppm I've been told, I've run higher. some meters are on a different standard and readings between meters with different conversion factors will be different.

You have to measure your waters PPM before determining your feed levels. It also helps to have your free water report from your utility if using tap water to know which minerals make up that PPM there.

yeah, thank you. im just measuing the water, then nutrients with the water, i heard there are certain levels you don't want to be at or its bad for the plant. im about 3-4 weeks in flower. and this is a good time for them.
