I contacted several new suppliers.
I have the opportunity to take all the chemicals you wrote above in small quantities.
Do I need all of them to create my own nutrition mix? Or would it be enough to supply some of them?
I also think that I will need micro elements other than these elements,but I think if I buy a suitable mix it will work for a long time.
thank you for all help
You can formulate a blend with less than I listed, but then you'll likely not be able to achieve your targets in Hydro Buddy, at least not precisely. I started inching my way into my nutrient collection and in the beginning I was only able to get pretty close to my targets, but I was also trying to supplement a premixed brand (Jack's 5-12-26). This brand was ok for cannabis, but I struggled when trying to change any of the elements, but that struggle lessened as my collection expanded. I then discontinued using Jack's and got my own chelated micros and made my own blends, some of which were good and some bad. I now mix to an augmented formulation of Megacrop. My blend has more P and less K.
So do you need everything on my list? No, but I still suggest that you aim to get them all if possible as your ability to adjust your feed, or even formulate a program for other plants will be greatly increased the more you have. FYI, here's the 6 micros I use;
I mix those precisely to Megacrop's formulation and my girls seem to likey like. I load those micros into Hydro Buddy, then input Megacrop's results into the targets field, and put it to make 500 gallons, then whatever the resulting weights are, I add into a half gallon to make the 1000:1 mix. Then it's just 3.78ml per gallon of nutes I mix, but for simplicity, I round that down to an even 3.5ml/Gal which makes quick math easier.
