do you have any Mo in that soil?

growingcrazy · 03-02-2018, 05:51 PM

I haven't specifically added any, nor tested for it in this soil bed. What are your thoughts?

Micropak has Mo I believe...I am still using that as a micro base for my foliars and teas until it is gone.

Also wanted to note since Easy mentioned the low pH. The last bump in K this round will come from Ksil. K, Si and a slight pH increase.

Spectrum is running Si, Ill post the number when I get it.

Mo I have used sulfates. However, kelp helps here. Micro pak and kelp seems to keep Mo up for me personally. Should start testing for it again though.

Kelp really is a great start to a balanced Micro approach. Good reason why pot heads have been growing with kelp for a long time. It's effective.

with 200 ppm nitrate your plant is loaded with it. gotta convert that into protein. you need an enzyme to do it which needs Mo

Can you give a full list of what amendments you are using? If you have a high P mix(and your getting it into the plant), your Zn can also be run higher. How high? Tissue sample and you shall know.

What would be a visual sign that it was lacking?

Just checked my spreadsheets.

Mo is in my weekly feed solution @ .3ppm.

That equates to about a .25 soil ppm addition over an 8 week cycle just from Micropak.

What are your thoughts on that?

You just mentioned tissue samples. Test your nitrate levels. Lower is better, zero is close to possible.

foliar is an excellent way to get Mo since oxidative state could effect uptake.

Mites would be a clue.

I will be doing tissue on peppers again this season. They are in a similar mix.

I still don't know of a place doing tissue analysis of Cannabis in Michigan.

Not a pest in site. I do have lady bugs though...

These plants received a couple teas with fish amino's and hit twice with a Ca foliar at the end of veg/flip. I would really like to see tissue #s.

Would you spray Mo in flower? if so, how late?

Thanks Doka...

Just be real careful of the sodium in that kelp!!!

It sounds like you need to go through your inputs, maybe test some regularly added ones. 117 sounds like a lot, but it depends on who is interpreting those numbers on tests. Spectrum says 4-11 optimum
I would also wonder if the zinc was unavailable in an earlier test somehow.

I’m guessing my zinc of 44 is from my 5-way mineral mix made of 20% SRP, 20%gypsum, 20% glacial rOck dust, 20% azomite, 20% wollastinite. Applied at 1.5-2 cups per cubic ft of soil mix
