Are you actually lacking CA ? I believe more often then not it’s more MG. You can use the search bar on here and look up “the recipe” and you will find an amazing thread for Jacks321I have seen some mentions of this and I am intrigued because I almost always seem to have Calcium Issues with my lazy too Many Top Offs RDWC with Smaller Reservoirs.
I feel as though at strong Veg Cannabis takes up more calcium and Nitrogen maybe they what can be keep up with.
Yes, I do realize factors like air movement and temperature LST and Intense LED's can all have an effect on calcium uptake.
And also Balance between antagonists i.e. Potassium etc...
I have seen some people (cant find them now) say 2-2 Jacks has everything they need etc...
Anyone help me here??? P.S> This is not a reference to Masterblend which I now also have a fresh batch and like it becasus it is designed to not have to mathmatically challenge oneself! Ha ha
Hey that’s what I wanted to hear but what I wanna know is do you grow in Hydro DWC or soil my concern is that that ratio might be fine on a reservoir change but how long can I top off with that exact mixture before I will build up levels too high of calcium or nitrogen and I guess there’s only one way to find out is to experiment I really appreciate you getting back to me with that especially since you’re not the only one that agrees that Jack’s doesn’t necessarily need extra magnesium as a matter fact the full 322 blocked out calcium. For me at some point but that was before I realized The current numbers recipe from Jack’s website it was actually closer to 3.2.75 That’s actually a big difference From 321I use equal parts 5/12/26 and calcium nitrate with zero epsom. More than 2grams of each tho.
I forgot to ask you can you please tell me how you came to bust the 2-2 instead of the 3-2-1 ???I don't do hydro. I use peat and perlite. Drain to waste. Fresh full strength nutes with each feeding.
Fed 15x a month. I use 4g of each by late veg and don't get leaf issues.
Peat is similar to hydro in terms of nutrients, but hydro people tend to use a lower ppm than I use for peat.
