I started off with the above PPM but over the year I've move to what's at the numbers below that in red.

For Hydro in general where do you set your PPM at the stages of growth?

Seedlings, Early Sprouts 100 to 250

Early Vegging 300 to 400

Full Vegetation 450 to 700

Early Blooming 750 to 950

Full Bloom 1200-1600


--------------------------------------
Seedlings, Early Sprouts 200-300

Early Vegging 600-800

Full Vegetation 1000-1200

Hey Lumix, The ppm's they give on the bottle and the web sites on there charts are to cover alot of plants in that range.Some strems dont like high ppm's and others want alot.If your strains are doing fine with higher ppm's are are ok with a higher ppm.I have one strain that like nitrogen and in flowering want more bloom with a little nitrogem.The numbers are to cover a range of plants. peace
