ppm level for this plant size?

What ppm nutrient level should these plants be at? They look they need to be darker so should i.bump it up another 100?, its at 500 in the last 2 dayz.

hello? are you guys too stone to read? lol help me out here

How old are they? What nutes are you running? Soiil or hydro? You'll get a bunch of different answers. I know guys who run up to 1200-1500 ppms, and others around 800; and those are all for plants in flowering. Personally, depending on your brand of nutes, I would up them to at least 700-800 ppms.

Yeah they are hydro, about 2-3 weeks old . the. First 2 weeks i was at between 300-350 using super nutrients a & b from canada. Its a learning experience u know? Yeah i should bump it up more i am at 530 as of now.

I'll just hit them with 1000 ppm...if u see leaf burn then back up some...easy pezzy

800 and adjust higher as required.
