Hi all ,
What would be a good ppm for an 8 week old plant 🌱??
I’ve never checked the ppm before so not really sure what it should be ,
Thanks in advance
Generally speaking going into flower between 800-1200ppm,slowly increasing bloom nutes up to 2200ish. But if you're talking about runoff that's different the high numbers in run off means you're ppm is too high and the plant can't take it in.
