Can the ppm in run off be more than double the solution ppm that u feed?
I’ve just got a cheap ppm pen yesterday and checked everything and my run off was something like 1920 and my feed was about 700(at work atm so guessing have it wrote down at home)
I’m getting a essentials set tomorrow because I don’t trust it and also going to buy canna flush today.
If you mix up your feed and the ec is too high can u lower it or do u throw it away and start again?
Also is the chart for ec range that is in the info for growing in coco at the top of the novice section for autos also
Thanks
