You'll like those, get them dialed into your space and they'll produce well. What first impressed me after the initial runs was the quality is beyond anything I've grown. Even the JTR that's just finishing up is louder than it's ever been and I've run it for 3 1/2 years. Awesome frosty, sticky buds and loud terps. But in addition to the quality bump, they're out-producing my CMH as well, nice.
I run 50% triple mix/50% pro-mix so it's a warm soil, not hot enough to run straight through so I supplement feeds every 2nd or 3rd watering depending on where they are in the cycle. Using AN A&B (no other crap/additives) at 400 ppm. It took a while to dial that in so I'm sticking with the AN, it's cheap for me at such low frequency and ppm feeds. Their 4L jugs last me months at a time, it's like 2x jugs of each A&B per year on average.
This past summer I tried the Jack's Citrus outdoor and it worked really well with plain tap water all the way through veg & flowering. Only problem with it is availability in Canada, they have no distributors/retailers here. Cheaper to buy on e-bay than direct from them but the shipping kills any price advantage. I'll be testing some Canadian salts similar to the Jack's next year, I talked to these guys and they look to have some legit products, available through some retailers in Canada, found one in Bradford, just haven't made it there to grab some. I use so little it's not a big deal for me but for someone using straight up pro-mix or hydro salts are a cheap and effective way to go,
I talked to these guys and they were very responsive, sent me a retailer in Bradford but they have others in the GTA and throughout Canada apparently. They're located in Brampton.
