For jacks you will need a form of calnit, it has 100% of the calcium and most of your N. I’d just start with the accepted mixes and then experiment w/ different mixes if you want or need to. ex: 321 or 3.6/2.4/1.0 etc…
I did a quick search and couldnt find a Jacks specific thread, so Im starting one. Im mainly interested in the hydro applications, but feel free to toss in anything you want on this general subject or even bring up other nutes - but - Id prefer to keep in mostly about Jacks or the other brands that use the same basic formula. Still, Im not a “stay on topic” fanatic, so feel free to wander…
I was wanting to switch to Jack’s for my vegging plants because I’m having trouble keeping young plants happy as they veg for 60 days. The organic amendments I use are great in bigger pots but not as good in Solo cups. I grow in Roots Organic soil in 5 gallon pots and I wanted to try something simple and effective like Jack’s.
Which NPK number fertilizer they make is the one people use the 321 system with? Is it the 5-12-26 or the bloom at 20-30-20 or both? I’m thinking I need both but I really…
I go back to them all the time
