That is my normal mindset as far as N goes. I will be curious to see the test results after harvest.

Do you see a direct correlation between senescence and soil N levels?

I have had plants cannibalize quickly at the end of flower with N over 110ppm, I have also had others that stay near perfect green in soils under 50 ppm N. More at work than just the soil N number.

If a soil has a Ca:N ratio of 100 to 1, Whichever element gets onto the on-ramp first dictates your end results...

Any of you see tissue numbers that don't correlate to the soil N numbers? What gives? Is this really an Mo driven result?

You want protein in the plant (chlorophyll). No such thing as too much. You do not want nitrate. No such thing as too little

some notes I've taken on Mo before

molybdenum is needed to convert nitrate to ammonia within the plant, feeding with mostly nitrate fertilizer will induce a molybdenum deficiency sooner than feeding with ammoniacal fertilizer. Research has shown that high sulfates can reduce plant uptake of molybdenum. Molybdenum is the ONLY micronutrient that becomes unavailable as the growing medium pH decreases...

molybdenum is closely linked to nitrogen that, its deficiency can easily resemble nitrogen deficiency.

Molybdenum is the ONLY micronutrient that is mobile within the plant

Doka is right, Nitrate is the issue not Chlorophyll of course

Mo is a tricky one. It also resembles a lot of other things too, aside from just N. High Peat, low PH, low life & lack of natural soils seem like perfect breeding grounds for a Deficiency to me in Mo which in normal farming in the ground isn't generally one.

I believe Canna likes Mo as much as Poinsettias do and they are a very good place to look for Mo research and leaf examples

It is not just Mo it is everything that makes up chlorophyll or every enzyme that is needed to cause the reactions that make chlorophyll. It is balance

Do not way overdo Mo. I use 0.15 gm sodium borate per 250 gal with CaNO3 as my N source. It is an ultra trace.

So humans store extra minerals in bones. Plants store it in leaves and stems. Of course balance is ideal so when the plant does draw upon its mobile minerals it won't get sick. But if you remove the fan leaves and excess can only be stored in stem and flower resulting in a sick and weak low yielding plant

And imo all of the good stuff, terpenes, thwhatever, are oils. They require a lot of energy. So destroying your chloroplasts late in the cycle seems counterproductive. You can argue stress response but a healthy, hydrated mma fighter stomps a dehydrated one. Imo

I wasn't trying to focus solely on Mo, def not my intention, I believe in balance for each individual situation always, lots at play - my guess is GrowingC has things under control just perfectly.... I recommend getting it via Alfalfa and Kale, as mentioned, safe way to go about it, no reason to overdo...

Mo is a unique key Micro though so I thought I'd point out a few things I've jotted down from past I thought to be interesting, it's interaction with N is also more important than some other micros.

pushing 7-8 week strains in Coco, I get this, perhaps.... Now growing NLD equatorial ones for 14-20weeks or more, the leaves falling off is part of the healthy game, if their still green near end your product is fkin terrible but it seems we're both after quite different things and end goals

[jidoka]

I originally mentioned Mo because of somebodies high nitrate levels in soil.

Another thing you could do is get carbon in that soil...jack up microbe activity and change the nitrate into aminos. Know how they say don’t chuck wood chips in your soil cause it uses up N...in this case that may be good
