cal/mag help

[Justinsane]

High all.

I grow in coco with canna coco A+B and been doing so for 2years and never had a cal/nag issue before but now i have a Black widow 4 weeks into bloom and this little biatch is showing me just that...cal/mag deficiency....

What shall i give her to help her out of it?

Can i use something we all have at home or do i have to go to my grow shop and buy yet another bottle of pricey stuff?

you can use epsom salts. Very cheaply. Some strains use more cal/mag then others.....

Is it a cal/mag problem or a cal problem or a mag problem?

edit: i even think i have some pills at home that is for us human to take...can i make it in to a powder and use that?

stick with the Epsom salts or liquid calcium depending on the issues your plants are showing... I had a problem with too much calcium by adding cal mag when all I needed was a lil extra magnesium, cal mag has more calcium than magnesium in it

as far as dosage use about a teaspoon per gallon

1/8 to1/4 tsp per gallon or 1 gram I believe is the ratio but not sure with canna nutes.

1/4 tsp a gal..... hit em a couple times then let them finish....
