Will be trying this recipe on half of my next crop.. Thanks!Nutes are Jacks 5/12/26, Calcium Nitrate, Silica, Fulvic Acid, Chitosan, raw cane sugar and citric acid.
1500ppm at peak Veg
2000ppm at peak Bloom. Then 1500ppm. Then 750ppm. I rarely flush at the end.

Those look delish! NOMNOMNOM.
Awesome!I'll make it easier for you. The nute ratio is important. The basic Jack's recipe is 3 parts 5/12/26 to 2 parts calcium nitrate and 1 part epsom. Jacks321. Then Jacks tells us it's not really 321 its more like 3.4:2.3:1.1 or something. So a lot of people go with that. It works, but it has too much Mg to use at high ppm. So yield for cannabis is limited by the addition of epsom in this popular recipe that was not developed for cannabis.
The solution is to eliminate epsom salt from the popular recipe. Part A already has plenty of Mg. You shouldn't run into Mg deficiencies because of this. So what is the golden ratio? After plenty of calculations and trial and error, I have settled on the simplest ratio that every stoner can remember:
1 part Jack's 5/12/26
1 part Calcium Nitrate
This ratio works well for the entire life cycle at the appropriate ppm for each stage. Be sure to use bioavailable Silica, not potassium silicate. Power Si and TPS Gold are examples of bioavailable silica.
