Perhaps it's too early now, as I still can't remember. Harley Smith was singing the virtues of something, that would open the pathways from passing one, to two, to dozens (I think he said thousands). The same stuff within the plant, would then hold the Ca, drawing it like magnets.
I know this chatter was close to the humic/seaweed ratio stuff, which I do follow blindly. It may of been the same talk. I'm shamefully lacking in this area of knowledge. The Osram guys visiting all the big greenhouses have only ever made one off topic comment to my knowledge (as lighting professionals). They are plant scientists themselves, and like me, surprised just what some of these things can do. Seeing them as important.
It's a thread we really should have. Personally, I have used some seaweed based stuff forever, and the humic since reading Bills great thread. I can't say much about the humic, but the seaweed I use is a great pH up, due to the K. I use it when I drop a clanger, or I'm hand watering something in. It's not great to put something so black through the hydro, and it settles on everything. My favourate feed contains it as standard though, and at lower levels, it's clean enough.
Back on topic, Ca can be helped by bottles, and I think it goes beyond chelation. Things like Superthrive just never go away, and while it's not on my list, I can't ignore it's stay in the market.
I realise my humic use, is probably to get the fulvic. Which means I won't use it in late flower.
I tried a Ca spray, but it just seemed to cover my plants in white dust. I didn't see any other difference, but then, I didn't have any issues anyway. Again, I was having a listen to Bill, who was saying a Ca bump reduced stretch. I just got Ca dust.
