I have been growing on and off for 20 years. I prefer canna products for feeding, along with canna boost (great stuff) during flowering I definitely saw the difference in yield and use superthrive as an additive all through the grow. I havent used canna boost with other products so read up on it. You have to be careful using cheap store composts there can be contamination with fungal spores and the like. I used some on one grow, had mushrooms growing in the pots, if that could happen who knows what else could contaminate your grow. Another thing I would suggest is adding superthrive to your feed mixes, it will boost the health and help against disease. Keep an eye on your PH levels on the feed, I had mine around 5.8 after I mixed the feed, that will vary with water temp. I have grown big bang before its not a pongy skunk but its yield is pretty good and it does have a nice stone, (I prefer a heavy stone of the indica varieties rather than satvia). Red Dragon is awesome, you'll have thc like a snow covering not just on the bud but a lot of the leaves too rather than just a mild frost look. The nirvana I wouldn't bother with. yield was poor on mine and hardly worth the pot space if your using the limited area of a tent. Look forwards to more updates on your babies....good luck
