Final update!
Last night I finished dry trimming the last of my 4 Jacks and got it all into jars. Ended up pretty good for a first harvest, total dry weight of 11.5oz off the 4 plants in my 3'x3' tent under a Mars Hydro pro II 800W (362W actual draw). Each plant ended up pretty differently with some pheno variations and some environmental effects.
The first plant I harvested (front right corner) had got really sick in mid flower while I was out of town for work. I never really recovered and basically stopped growing at that point and matured much earlier than the others. It was also one of the 2 plants I experimented with a bit of LST on. I only got 15g off of it. The bud I did get off it is pretty nice though, good aroma and taste.
The second plant I harvest (front left corner) was by far the largest of the 4. It exploded and grew 2 feet during the week I was away. It was the best yielding plant at 166g. It's size overshadowed the other 3 plants in the tent which was way to cramped for 4 plants of this size. If I had more space I am sure all 4 plants would have yielded much higher. The terpene profile of this plant was quite different than the others as well, with some time in the jars bringing out a earthy chocolate aroma in contrast to the citrus grapefruit smells of the others.
The third plant I cut down (back right corner) yielded more than the first but still only 37g. This plant started life with a bit of mutant leaves, but grew out of that eventually. I had LST'd this one as well. This one had the best aroma of the 4 though with a very grapefruit citrus smell.
The 4th plant (back left corner) did pretty well despite being crowded out of most of it's corner by the big plant in front of it. I couldn't even see it for most of flower. Ended up pulling 105g off it. It was a extremely leafy plant and took quite a while to trim. The buds had so many sugar leaves you could barely see the flowers. The buds fron this girl have a citrus aroma with a bit of diesel.
I have to conclude that this strain does not respond well to training, at least in my situation. The two I very lightly LST'd did way worse than the two I let grow naturally. A lot of the discrepancy I am sure was due to being overshadowed by the big plant, however the 4th plant still did pretty good despite being shaded the most. It might have been better had I LST'd all 4 and kept the canopy more even, but then they might have all underproduced as well. Interestingly on all of the 4 the biggest buds and tallest colas were not the main stem even on the plants that I didn't train.
I am still curing the buds but preliminary smoke has been pretty good, the effects are remarkably similar to how I remember Jack Herer being with a very clean high with good energy, clear focus, and inspirational creativity. It also come down super smoothly with no tiredness or headache. I can smoke this all day and not burn out!
I used half the sugar trim to make a salve which turned out pretty nicely. I plan on giving some to my wife and my mother for mothers day.
Anyway can't thank the AFN community enough for all the information and support I have aquired through this site. It took a lot of learning to get this far. Thanks to all who helped me and encouraged me along the way:

for sure :smoking:
cracking harvest 
every grow is a compromise,unless you live in the tent :smoking:so considering you was out a town a few days,fantastic result 
hardly your fault 
best plant is a belter 
average weights not to bad either
