About being a Calcifuge, I wonder here, if you may possibly have the wrong perspective on what the label Calcifuge / Calcicole means. That categorization is in no way connected to Calcium "Use" or "Requirement" for plant species. If it were, then ecologists would not have been able to group all plants into just 2 categories. Rather, it was originally brought forth from noticing species diversification in differing soil conditions; which eventually led to this "bulk" classification. As well, the connections with these 2 plant types and their corresponding sensitivity / insensitivity to (Al,Fe,P,Ca and Mn) was also realized early on. However, the exact reasoning and function behind this differentiation took quite a bit longer for scientists to deduce.Within the leaf, Ca follows the apoplastic route of the transpiration stream and accumulates in either the mesophyll cells, trichomes or epidermal cells adjacent to guard cells, depending on the plant species. Both the [Ca2+]cyt in guard cells and the closing of stomata in detached epidermal strips are sensitive to apoplastic Ca2+ concentrations within the range of [Ca2+]xylem."
If we then put together all of this information it would make sense why Cannabis and Calcium issues seem to be so common
This jives with my (organic) ag readings. Not many papers, most go far beyond my pay grade and I can barely interpret them.I know from experience that increasing the calcium supplied to cannabis improves its health in many gardens, I presume that if you had tissue analysis you would see the marked increase in shoot calcium content coincide with increased calcium fertilization.
I think often times calcium deficiency is misdiagnosed by cannabis forum participants.

Calcium is acquired from the soil solution by the root system and translocated to the shoot via the xylem.""The Ca concentration in xylem sap ([Ca]xylem) is influenced greatly by [Ca2+]ext, and [Ca]xylem between 300 µm and 16·5 mm has been reported.
Yep I'm aware of that abstract and the only paper done on this. Though, it would be logical to assume that surplus Ca storage in trichomes would be a stress response; yet again irrespective of Calcicole or Calcifuge. If we were able to access the entirety of the paper, then it could be seen to what level they were noticing differences. However, note that they were not pointing out the novelty of a plant using trichomes as a stress response; but to convey the possible connection to this and further reasons to why Calcicoles may be able to tolerate such high Ca levels.My point regarding trichomes is that " the ability of some calcicole species to tolerate high [Ca2+]ext may be related to their ability to accumulate Ca in their trichomes (De Silva et al., 1996, 1998)."
kinda gonna go backwards here with the response.
Maybe it would help to clarify what was said with the nails. (paraphrasing) "You want an old nail that's pure iron, like before they were round; but doesn't have to be, just pure iron. The nail must be starting to rust, otherwise it will take forever for it to work, but you don't want it covered in rust. Then just stick them in the soil around your roots......since you're having iron problems I would put about 8 in there"
Just to state about what was said at least; that's how it was conveyed to me back then. From what I can find, Fe Chelates were first patented in 1957 and the first fertilizer patent is from 1959. I would presume the rusty nails were used more common before 1960 then.
With the last comment, though; I noted that the Camellia that Sea mentioned (doing the same with), is a calcifuge I guess.
Ok, that's out of the way.....
@Quantrill I did not mean to come off argumentative and I owe you an apology if I did. I would be lying to say that there was not an err of sarcasm with the "props"; however it was an honest statement, as from a debating perspective it was a great pick. I do respect you bringing up opposition and, if you believe this, I am / will still be open to learning more with this subject. I did mention that it comes down to conjecture, experience and logic so I do still consider this a theory and is thus just "my perspective"; as such, I should have put in more "i feel", "I believe" and IMHO as I tend to be a bit poor with this (when spitting out info).
I suppose on a side note. I did not intend to bring up the Calci-XX thing when starting this thread; nor did I have particular intentions of bringing it up at all. Whereas I have brought things up in the past as simply a neat find (which I try to point out as such); this particular thing I had / have spent more time on. When I used to do research for a company, any new idea would have a "shootdown session"; before any resources could be devoted. I suppose here and to make a relation; I would be at the point of approaching the team (which i kinda did here xD) and consider the theory "defensible".
My apology again to you Quantrill or Anyone who might have felt drama from this.
What I do know is if you get the temps and humidity right most all the other issues go away. I think it all has a lot to do with ca, vapor pressure deficit about 10 and everything seems to work out.
About K, I kicked it up to 2000 ppm's once just to see, I didnt see any ill effects on that plant. That was with a strain that always seemed to want more nutes in general.
