other than carb loading, which has to be done properly to work, nutes are not a good plan to increase yield. The amount of nutes you need is going to be determined by the size of the plant and how fast it is growing. The speed it grows at depends on the amount of sugar production. As the plant's growth increases it will require more nutrients, but it is not the abundance of nutrients that will cause increased growth rate, it is the availability of light and space primarily. This means that to hit your potential you will need a certain amount of nutes to feed growth, but once you hit that perfect point no additional nutes will cause the plant to grow any faster, you would have to increase light, and then look at bottlenecks like co2/oxy, nutes, pot size, etc to increase yields.
There's a lot of misleading advertising and flat out misinformation on additives. No one mentiones that too little nutes mostly restricts growth, but on the other end an overabundance can kill a plant quite quickly.
