so i still dont know about your nutes, so a general word on that. We are (at least I am) heading for specific ratios of nutes during the grow. We do have those ratios on our nutes, but they are in %weight. So if you want to know the percent in liquid measures like ml you need to do some math.
For the process best is to have a large amount of liquid, the let you have the more the variance later on. If you have spmall amounts only go the second way mentioned above, but take as much nutes you have to get to a "narrowed down" result.
For easy calculating and explaining I chose 1l of nutes.
Weigh that 1l (1000ml)...it will be higher than one kg..depending on the concentration.
so lets assume 1l grow nutes weights 1.100g and has a npk ratio of 3-1-4 and bloom weights 1.300g and has 1-4-6
but you feed and add in ml. To transport and compare for mixture the weight to liquid you now simply divide by the weight (1000/1300) so approx 0,91ml veg weight 1 gram and 0.77ml bloom weigh 1g.
You can also go the other way and take a good scale and watch for how many ml are 1/10/100/1000g..the result in the end should be the same.
Now you can add/multiply the ml.
0.77ml b+0,91 g equal a ratio about 4-5-10
2x 0.77ml b+0,91 g equal a ratio about 7-6-14
and so on..you are free to do combinations that may better suit the plant. You wont always get what you want, but you come near optimal with the right nutes, but if you run a nute line and see the same lack every grow, you may decide to add this special lacking stuff at a time.
This is one of the cheapest tools available to shoot for best/wanted ratios...then for strength i heavily recommend an ec meter.
So don't shoot in the dark when flipping nutes, so some calc.
For who runs when which ratio...perhaps do some more science.
Hope i could explain a little..my daughter says I am very bad at explaining, so please apologize.
