Should I Use Cal/Mag During Flower?

[Dman91]

Ya I wouldnt change anything. They look healthy. Was that leaf you pulled not getting light?

It was towards the top of the main cola. I figured it was a small cal/mag issue but im not sure I should worry or if I need to fix it

I would keep using it all the way to flush. Maybe even more. How close is the light?

Was that leaf you pulled right at the hot spot directly below the light?

I use Cal mag all the way to the last week of flush I’m in coco perlite 30%70% mix .Od

Im having the same issue, how much cal mag do you use. Im in coco/perlite as well. Thx

5ml per gallon is recommended, I use 2.5 ml and slowly go up until flower then I keep it the same dose until last week of flower, I just flipped this morning and am lollypopping already. Got 1 clone as the plants are on the small side this run, one may be an Indica strain. SS

Nice, ive been giving 5ml frombthe start of feeding. Ive tried to increase it to 7 ml with no reslove. Im 4 weeks into flower and dont want to loose the plant. Im a newbie first grow and im thinking about attempting to transplant into soil. Ik it sounds crazy but it would be a last ditch effort.

Fairly new grower here. I am curious when I should stop using cal/mag with my feedings. I am using fox farm ocean forest soil. The nutrients I am using are the advanced nutrients sensi bloom line. My plants are both looking healthy going into week 3 of flower. My only problem is that I am seeing some deficiency. Is this going to be a problem or should I leave them be. Any help is greatly appreciated

Around week 4 I switch from cal/mag to just epsom salt. I have a chart I’ll have to find and I’ll post it which shows when the plant ya demands raise and fall. If this is wrong someone speak up!

Personally I have cut my calmag use back during flower to reduce N.
At this time maybe 2ml gallon using ro water.

Haven't used Calmag in probably 10 years.
If your water is decent you shouldn't need it. If water void of nutrients, you're better off using a standalone Calcium product like Calcium silicate or Calcium Carbonate imho.

Most nutrients on the market today have plenty of Ca and Mg as well as a complete micronutrient package. I honestly often see people using calmag have issues with excess Ca and N causing a cascading effect of nutrient imbalances.

The only time I'd consider it is if you're using distilled or reverse osmosis, or rainwater. And even then I'd only use a product that contains no Nitrogen.

 

[ImpulsiveGrower]

It's interesting that you would cut the Calcium, right when your chart indicates peak demand.

I bet the quotes missing.. never seems to work

The chart indicates that yes it’s at its peak but then you can see it slope downwards at that time as well.

 

[WGH]

Yes! you add Cal-Mag in Veg and Flower. If you are using RO water then you should be putting at least 300 PPM of Cal-Mag.

Hello my friend I see you are growing Bruce banner . what number is your Bruce banner ? I have a fully documented series of bb# 3 mothers and clones. I have vids of every week from germ to jar!! I am currently pheno hunting Bruce banner #3. I have had the issue you are experiencing bb#3 need calcium and magnesium at a rate of 2 to 1 of normal plants, meaning when feeding bb#3 you must double calcium and magnesium when in veg. When flowering bb#3 needs half the regular dose of nitrogen and phosphorus at 2 to 1 as well. Bruce banner also must be defoliated regularly or it will begin cannibalising shaded leaves faster than normal plants. Please check out my grow forum. I have spent along time figuring out bb#3 and you are one of the few that are running Bruce banner. I would like to help you with advice and experience I've accumulated about bb#3. If you need help hmu fr

Check out my grow vids and make sure to look at all the pages there are 11 pages of bruce banner #3 grow info. Take a look lmk what number banner you have also

Any deficiencies during flower will fk your quality and harvest drastically. Run cal-mag up until flush, 75% concentration during the ripening phase.
