This is why I get folks to run soil analysis correctly, using procedures for the type of media/soil that one is in. Those that have gone this route and applied their Ca up front in adequate quantities against K, Mg and Na, see excellent results.
Having more K than P, same issue, hard to catch up on that one too.
So yes, roots are roots. Just that if a Mom is malnourished, her clones are not going to form callus on the cut. Many seeds lose viability or have problems for the same issue, not enough reserves, especially Mn.
I will take some photos in February of a couple of grows that I work with to demonstrate my point regarding callus formation. I will probably post those in my thread though... slownickel lounge. Check it out. Lots of analysis, science, results!
Iím looking to expand my knowledge. So Iíll be over your way, to check out your thread. And I would very much like to run a soil analysis of the mix I use. So I look forward to learning how.
But in the meantime, what of my question? Such discussions only seem relevant to a homogenous garden with clones of one particular var. (To say nothing of abstracting away from environmental conditions.)
I agree with others who have said the variables are otherwise boundless - and I say this only because whether from clone or seed hasnít been established - unless I missed it. In other words, is any of this relevant if growing from seed in a non 100% controllable environment? And under what sort of lighting? Artificial, natural? Do Ca requirements under natural lighting equate to the same under artificial?
It may be true that most mixes or bottled additives lack sufficient Calcium... but relative to what? One pheno may thrive and find all that is necessary to flourish in a particular medium, whereas another - or others - may suffer a tad; and at worst, struggle. Or, they may all shine.
All Iím wondering is if I up the Ca in my medium am I going to see full success growing from seed? Irrespective of phenotypical expression?
