Calculated ppms rarely equal tested EC/ ppms, I'm pretty sure calculating the EC from bottles is a little more complicated. Canna stats is best for finding a good ratio and then diluting to the correct EC.
because 4 is bigger than 3.......?Also I don't understand how you are getting higher P ppms than K ppms with a bottle npk of 5-4-3. What a strange ratio
hey guys, bottle NPK shows N, P2O5, and K20.because 4 is bigger than 3.......?
the elemental ppm ratio is 5-1.7-2.5. I find this ratio to be quite strange as most cannabis ratios I've heard are around 3-1-4, with some variations on media.
at 200 ppm I can not get my mothers to yellow a lower leaf at all. I would literally have to give them straight water for a week I think.
I've tried to see how low I can go and it seems that 50 ppm of nitrogen in veg cuts is just fine, as 100 ppm of nitrogen in flower is ideal as well.
