Question for the powder people, Jack's people and/or Tint Eastwood

Yeah, the 2-part is good for sure. It's one of the best. I have it in the cupboard, just in case needed.

Here’s a pic of my bag of the finish. It says depending on your source water you may have to boost the calcium with their CaNO3.
It was the first place I saw it and it’s likely that @Roger A. Shrubber is right and I got old product. So it might be different now, but it won’t matter much to me, just going to use the 321 from here out personally.
I wouldn’t doubt that the plant would have lots of calcium as long as you fed it well in flower, like @rkymtnman said.

If you don't mind liquid ferts, I could recommend a nice "finisher" for you. It's called "Uni-One" and it's made by Uber Nutrients. It a complete fert which in undiluted form is very acidic. You add just enough to get your PH were you want it to be. For me, with PH 6.8 tap water, it's about .5ml/liter or .15ml/gallon. It works great, provided that your plants have remained healthy up until that point. If they are deficient already as they near finishing, I would not recommend this.

Here's a link where I posted the minimum guaranteed analysis, if interested. Unless you are commercial, one gallon of this will last a long time.
