I'm pretty sure most of you have seen these diagrams, from an great US Ag fert producer:

This "hoodie"-type of upping and downing is typical to some nutes. One could say the "pre-loading" already began in late veg and topped at the phase of greatest plantmass gains. Physiologically this makes sense due to lots of new cells being created.

Would some of you treat Ca rather like S in this regard?

Isn't that graph from hemp production? just saying seen it shot down online a bit as old info.

Anywqay in the end I was originally just trying to push the point of dropping nitrates at the end ie. flush without dropping out Ca by replacing the Cal nitrate with cal chloride or cal sulphate micronised. for eg.

I don't think anyone considers that flushing. Maybe crop steering. I do agree though. Most nutrient lines are asking you to red line nitrogen to supply adequate amounts of calcium throughout flower.

Biologically it's the same species, but I doubt hemp (fiber- or seedhemp) need increased S towards end of flower. Heck, fiberhemp isn't even flowered out - its quality sharply decreases with the onset of flower so they select cultivars to flower very late and strive to cut it right early.
(There's mixed usage genetics though...)

There is one person I know of. He has a PhD in Biochemistry focused on plant physiology, did research and worked for the bigs for years. I could go on about his credentials. Anyway he's my go to for advice and he doesn't flush. I've had a ton of chemistry, physics, biology etc... however I practiced on humans not plants and I see no reason to 'flush' and by flush I mean 2 weeks at the end starving your plants of nutrition in hydro and I could go on about soil but won't bother since I don't use it. But that's part of the problem first you have to define exactly how flushing is defined.

Frankly if you want to flush your plants, or do anything else, enjoy they are your plants. We've discussed this before. I have no problem with what you do. But we do have 1 person here who has the actual ticket to that discussion.

Do you have a source for that graph i struggle to find one. Yes biologically same species but one is grown for its fibre one for its flower so obvious differences I would assume

It's broscience - "loading up Ca" (lol). How is the plant going to be loaded up?!? And exactly this macronute which the plant can only load into the phloem in minimal amounts, and neither can it retranslocate it. As there is no need - the soil outside is full of Ca.
Preloading other macros (NPK Mg) during veg is what some are practising.
If that is the same guy as on ICMag you can just scrap what he says (it's evident he just makes stuff up and has zero AG education).

how funny poor kassiopeija , i'm sure slow would burst out laughing to see that

You will listen to an agronomist with more than 40 years of experience.
Taking care of soils in more than 20 countries, which breaks records every year in its crops in different cultures ???

Or

Are you going to listen to those people who keep wanting to say that they know more or do it better?


More respect with slownickel.

draw your own conclusions
and be careful with those forum experts who claim to know a lot in “theory” but never did it in practice.
