I did the Blue Mystic in my last grow. What a princess huh? I learned the hard way about her nutrient needs changing dramatically from veg to flower. Definitely no beginner strain, but maybe better suited for soil or organic growing. Outdoors with her would be a completely different grow.
I ran into a slew of Magnesium and Potassium deficiencies during the first 3 weeks of the flowering; from my research it appears pretty much everyone does. Then a little phosphorus shortage will show up during week 3 (but I was slamming PK 13/14 so I managed to sidestep most of that problem), and then back to the magnesium shortage for another 2 weeks. She's really sensitive to temperature fluctuations also, and doesn't do well with heat or high humidity at all. I had root rot set in on one plant, so she's not very mold resistant either. Veg is a breeze with her, she stays short and is very pretty. Flowering is a whole can of worms though. The smoke was great, but not rewarding enough for me to want to grow her again any time soon.
Wappa is in my next grow, with some Sensi Star, Motivation, and Rocklock. These genetics are all "cousins" or more directly related so I figured growing out something closer genetically speaking would be easier when it came to mixing nutrients.
Good looking grow though. You stuck it out with that BM and that's commendable. If the seeds weren't so cheap, or the pictures so appealing, I imagine there'd be far fewer people growing it out. Next time I'm going for some real Blue genetics because if I'm going to learn something hard to grow it's going to need to be a bit more flavorful.
