BombBudsstarted grow question a year ago
Hey people! I would like to use one of your diaries as a guide. Most of them grow several plants at the same time. I would like to grow 6 larger plants in a 120x120cm time. How can I convert your fertilizer quantities if I have to water more with larger plants in larger pots?

you deal in concentrations, which scales as is.
you can calculate ppms, or use weighted average of NPK values relative to individual dose of a product/total dissolved. These are per gallon, liter or even perticles per million, so it's going to be the same for you.

The diaries are listed as a ratio, ml/l or g/l or gal. it is scaled. but not everyone does the math right so I would not go off of that 100%, look at the components they use, eg grow, bloom, micro, and then do you own calculations.
I would use the PPM or better yet EC scale to calculate the concentration of the feed and go from there.
1 EC = 1EC no matter the device, however PPM is a calculation and sometimes 1EC=500 or 640 or 700 PPM depending on your region.
VPD is also at play, plants that drink more need less feed contention in the water as they will be taking up more. Listen to the plant and watch it showing you signs and symptoms of to much or to little. Most brand provide a feeding chart and that can be used at different strengths, 50% sometimes or even 35% if you lack a ec./ppm pen.
If your using amendments then this is a different ball game as you tent to just PH the water and mix the rest of the stuff into the top later.
Good Luck!
