No use for Cal Mag during late Flower?

Sorry I was taking a shower when I heard it like last week, I don't know where the source was. I guess with everything that comes with cannabis it's an issue that needs alot of context and info. Sorry for my dumb thread.

I think he said something that CalMag was really just for Cell walls early in growth, and that it's not really needed in Flower. I think it was a Garden Talk with Mr. Grow it.

I always just assumed cal-mag regular usage is for coco growers only? I taper it off with silica, about 3 wks before harvest

Really? The plants Cells, on a cellular level still need subsistence during flower stages also. Silica is a good source. Easily available via diatomaceous earth. And cheap but effective. For realz!

Heard the program on u_tube
He was mentioning that Cal-mag suplementation was not really needed flowering outdoors in soil supplemented with pelite due to its decomposing and feeding the plant naturally.
It was Mr. Grow it.

I use Calcium Nitrate as my Nitrogen, and Calcium source, and Epsom salts for my Magnesium, and Sulfur source. So I dont use Cal-Mag. Sulfur is very important in the end stage for production of terpenes. On an 8 weeks strain I give ever increasing amounts of everything until week 7. Week 7 all nutrients are cut back, but nothing is eliminated totally.

100% agree with sulfur/terpenes.

Calcium carbonate may act as a pH buffer in mid to late flower. It's dissolvable under pressure with CO2, like in a Soda Streamer. The carbonic acid help to dissolve it in to solution. It may however take a couple of days for it to completely dissolve. Keeping it cold helps. There's a lot of ways of regulating pH and a lot of ways to the finish line.

It all the depends on the medium, style of growing and the mineral ratio and content what actions you may need to take throughout the grow.

That being said almost any synthetic complete mineral based nutrient line work in any medium with drain to waste with only pH adjustments.

I don't supplement any CalMag during any part of my grow. So there's that. I wouldn't listen to 99.9% of stuff you hear on YouTube.
