Listen to a commercial growers take on it I guess.

I didn't get much from that video other than his personal opinion. He sounds like he's a fan of flushing, which would explain his opinion on the matter.
I'd like to see some links to scientific information showing proof of what he's talking about (You are welcome to PM me the info).
I don't want to get into a large discussion about flushing in this thread since this is a sticky ment to assist people in the harvesting process.
It's not really a discussion based thread for theories and personal opinions, it's ment to contain purely factual information.
I have presented my proof of how nutrient storage, transportation and consumption within plants work, you can find it (as I've already mentioned in this thread) if you search for my nick and check my previous posts.
I'm repeating myself, but for the sake of the argument I will.
Cannabis nutrient storage and transportation around the plant is very complicated. I'm not fully explaining every aspect of the processes in the following;
Basically the nutrients are "stored" in the leaves and roots, fan leaves more so than sugar leaves.
Stems also contain a lot of nutrients but this is more to the fact of the xylem, phloem and other plant mechanisms being the main way of transporting water (and therefore nutrients) around.
The ratios are different depending on which nutrient we're talking about and also which supply (deficient vs critical vs abundant).
For example nitrate ions are 'stored' ~3:1 in leaves compared with the roots.
Whereas phosphate ions are 'stored' ~2:1 in roots compared with the leaves.
Suffice to say that there is a reason why fan leaves (and roots which is readily visible in hydro grows) react to overfeeding and underfeeding first and most severely.
The calyxes themselves do not contain an abundance of nutrients at any point in the growth, unless you heavily overfeed your plants. And you have to overfeed
A LOT.
Most abundance nutrients by far end up in the leaves, roots and stems.
Cannabis plants are highly efficient, they use up the nutrients supplied to the calyxes very quickly, almost entirely eliminating any chances of nutrients building up in the calyxes, except for extreme cases.
This is evident in the scientific information I have provided in past posts.
I will just end with saying that I don't want to see any more arguments in this thread, I have deleted some of your posts, Lucius & Simon.
I hope you understand that it's so we can keep this thread on topic, easy to navigate for people who need help and useful throughout.
