Got some Epsom salts and Folier fed it going to do it again at lights off and then wait till next feed in 5 days and I will water the soil with the Epsom salt and nutes

Is this ok for calcium or is it toooo strong in N

Gotweed- I know pH pens well, and they autocalibrate for different solution temperatures, not for pH itself,... not that I necessarily think it's off, but you can't use other random liquids for calibrating, it must be a specific, stable solution made for this purpose...it's readily available, and some should have come with the pH meter when you bought it...

but from google i found someone who had ph checked their water at different concentrates and for my concentrate the water would have ph of around 5

...sorry mate, but no correlation can be made between what some other person gets and what you get-- water is not the same, in ppm's, pH, etc.,... and a pH of 5 is waaay to acidic for feeds! ...epsoms will be fine, but keep in mind that they are MgSo4 only, no Ca in them (foliar spray at 1 tsp/gal),...**** whoa! holy crap, what is that stuff you posted? Yes, there's also way way too much N in there (N= 15%), but worse, the Ca source is CaO- calcuim oxide, also called quick lime... it's caustic nasty stuff,... I don't know what that fert' is really for, but if you use that on your MJ plants you'll be taking an awful risk! Absolutely not recommended! Find another source of Ca dude,...

What Waira said, plus as said before is most proberly more a Magnesium Def and not Calcium and that stuff has no Magnesium in it all, best with a Canna specific Calmag product.

Cool I'll leave that be and just use the Epsom salts and crush some egg shells

Why not google hard water areas where you live.

If you are in a hard water area your be getting a fair amount of calcium in your water already.

I don't know where you are so I have supplied some examples

Hi Arty, nice info but I would be a bit cautious. I don't think the chart takes into account what treatment is done by the local municipality. We have well water and spring water on our property and they test different and also vary with time of year
