Auto flowers “jacks”advice?

My auto girls are ready to go in ground in promix Mx mix I plan on using Jacks 321, Jacks professional nutrients. What’s the best npk to run should I run 2 part?? Or the same all the way through I plan on using other nutrients stacked like cal mag/ silica and others. Any help would be much help

Lots of people using jacks around here. Couple threads on it already if you do a search.

In theory the base 321 is all you need. I only use the jacks tap, calnit, Epsom in my flood drain hydro. I did not use any extra cal mag and had my best results yet.

So p much same thing all the way. Read your plants. The question itself is hard to answer because every plant is different.

The best answer is do what the plant wants. Not what you want. If the plant wants more cal mag then do it. Otherwise why add something that may mess things up.

Got 13 ounce from 2 autos in 2x4x7 600hps

I ran Jack's 3-2-1 start to finish. Started at 0.4 EC and finished through flower at 1.2 EC. Also with ArmorSi. Flowered two phenos of the same strain in 1 gallon cloth pots of coco. Weighed one up after drying at 6.4 oz. Beautiful plants.
