Can I double nutrients to get the right numbers?

[craftygirl]

I am trying to get my nutrients to 2-7-7 for flowering and can't find those, however I do have a 1-3.5-0 and a 0-0-6, so I was wondering if I doubled the 1-3.5-0 would it be 2-7-0?
I am growing in soil.

Thanks

I'm not sure if that would work or not (though it seems like it might), but the easiest way to get 2-7-7 would be with "Schultz Cactus Plus 2-7-7" that is probably available locally and inexpensively. It might be the route I'm going to go.

Sadly I live in the middle of nowhere in Canada, so my options are very limited. Even ordering online things take forever to get to me, like usually over 2 weeks. I haven't been able to find the schultz cactus, I was looking for it forever around here.

I'm sorry I can't help, then...but the arithmetic looks right for combining the two -- but I think the possible danger is in determining their relative volumes. I hope someone here has experimented with this enough to help you.

im doing something similar with fine tuning my nute/supp scheduling.
not simple when ur new, lol.
when you target a specific custom npk ratio its better to know the concentration (ppms) before you go mixing it all up.
i start by mixing 5ml of each component to 1 gal water that was tested before mixing. subtract plain water ppms from total mix ppms and record the result. now its simple math to hit your npk ratio and stay within an appropriate concentration range for the size of your canopy.
hope this helps!

You should be able to do what you're suggesting. Make sure that the fert doesn't add any other micronutrients as that might be an issue.

How does one go about measuring ppm?

[D.A.A.S.69]

With a meter or some strips.

hey craftygirl doubling your nute only increases ppm it will not give you 2 77 you would be far better off to buy something that is made for weed and wait for it to come in sorry just trying to help
