I have to bump this thread to ask what was the nute sched you used with this? Flower nutes from the start or veg nutes for a couple weeks at the start? I did read where the big bang mango was one of the best producers of the new wave of auto that came out a couple years ago.
This was when I was mixing ResinRubber's Soil and Using Neptune's Harvest to feed them. I used the 2-3-1 Neptune's and Molasses.
