When to stop CalMag???

[Surfr]

What's up farmers! I am just curious when people stop using calmag? I cut it out at 6 weeks flower. What's everyone else doing???

Gracias!

9 to 10 weak strains I cut it out week 6 , 8 weak strains week 5..Im usally at 200 ppm in veg 150 first 3 weeks flower then 100 and then cut it ...JACK

I use it up to week 4

If used to long during flowering it will lead to harsh smoke

Thats from my experience

I use it up to two weeks before flowering ends, at 1/2 dose from week 6 onward (10 week strain). Seems to work fine- never have a cal or mag issue. Good flush is important at the end...

Really depends on a few things for me. How long will a particular strain need to be run? How much does that strain need, or how strongly does it use Ca/Mg?

My goal is to get it dropped one month before chop, and let them use up whatever remains.

i dropped it at week 4 this run, and the girls seem to be ok with it. save for a few rusty necrotic spots that showed up this week.

prior, i never cut it and went straight through harvest.

i run 10ml for my ogs tell flush, it has enough nitro to keep them going in later stages.

Hey I know this is like 12 years later but isn’t that super low ppm? I thought it’s supposed to be around 1,000?

probably just talking about the ppm of calmag itself, not the entire solution

God sent response. Thanks

just switch it to magnesium sulfate for the last 2 weeks flowering.
