Hard to say if mammoth did anything. I don't think I'll ever use it or recommend it to anyone to be honest. It's just not worth the expense, by far the most expensive supplement I used and nothing to definitively say whether it helped.
I stopped using these nutrients half way through the grow bc they took too much time to use with my schedule. I switched to new millennium and seemed to have great results.
This plant took a lot longer than I thought it would. In total about 13 weeks of flowering. I think this is the bb#4 phenotype which is more sativa I believe. This plant was fairly easy to grow. I've already got a clone from the same plant back in flowering.
I had some issues witg gnats and found a couple mites the other day but other than that this grow was pretty flawless. Very dense, light green, frosty buds.
I tried a little of the GDP that I cut off and dried about a week ago and it's very potent for sure. Tastes and smells like grape candy. I will update with dry weight when it's done drying.
There's some nice purple coloring in the tips of the buds. Overall I'm happy with the results. I'll pay a more in depth review after I get a few weeks dry and cure.
