just curious if he liked them...and if he used the Duo throughout the grow....no biggie. I just started using it.
Question for those that have used Jack's Classic 20-20-20

Thanks brotha!!!
it always amazes me how folks can take something that's ridiculously easy and foolproof and make it needlessly complicated. All to what end?
I use jack's. Max concentration in veg is 1 teaspoon per gallon for feeding with every watering. To answer an older question, i use pro-mix (though, virtually any medium will do in a pinch) and jack's. No additives, no magic potions, no improvisation, nothing mixed in. Some of the results are link'd in my sig.
As a rule of thumb for a new grower, the more variables you introduce, the less your chances of success. Good luck.
Edit: Let me talk a bit about working with the stuff. Like i said, the product is essentially foolproof. Below is an example of seeds 2 weeks from sprouting after being fed with jc from day-1:
as you can see, all the plants have 3-5 nodes within 2 weeks of sprouting. They're fed with 1/4 concentration of jc (ie/ 1/4 teaspoon per gallon) for the first 2 weeks, then the concentration doubles in the next watering, doubles again in the one thereafter, and then stays constant at 1 teaspoon per gallon.
Starting with a rooted clone: First watering is 1/4 concentration, then it doubles with every watering until max is reached. That's it.
That's how fucking easy this is. No variance at all. There's elegance in simplicity that translates directly into big yields.

What is your water source/quality? well, tap, ro? what are your ppm/ec after mixing up jacks? I just made the switch and im eager get this going!

I use tap. It reads ~120ppm. At the height of flowering, the watering solution reads ~800ppm.

Thanks Simon! i appreciate the feedback
I generally run between 8-1200ppm I find its pretty forgiving stuff. I use Jacks pro 20-20-20 And blossom boost 10 30 20 and just buy in 25lb bags. I used to use GH 3 part and tried various other prods, but it was a nightmare to keep everything balanced and I spent more time chasing issues and dumping CalMag in repeatedly.
Jacks is a no brainier, you feed it all purpose in veg, when ready toss in flower go to blossom boost, if you ever start getting slight N def hit with all purpose 1 time and you are set. I may try out their high performance, which is a 25,5,15, which is a little closer to the 3-1-2 ratio I'm looking for in veg, but the all purpose does seem to work pretty well.
