Hi WisdomKarp,
It's a shame your Blue Mystic isn't doing well. Don't give up just because of one grow though!
The pics below are my Blue Mystic auto. Shes ~54 days from cracking the soil now. I'm thinking about harvesting in the next week or so, depending on the trichomes (I estimate 95% milky, 5% clear as of 10 minutes ago).
For the first 30 days or so she only had 45 watts of light. As time went on I have upgraded my box, there was no ventilation until around a week ago so I'm quite impressed at how she has coped. No nutes added, no ph checking, just basic potting soil I picked up from local home depot (note: it did say that there were nutes already added to support 10 months of plant growth). I did do a little bit of l.s.t however, it was around day 40 when she was about to outgrow my lights. I bent the main cola down. Apart from that, all I did was water it with tap water every few days.
Some issues I had:
- She kept growing into my lights, as a result she has burns everywhere, as you can probably see.
- I believe she has a magnesium deficiency, as there as brown spots on a lot of the leaves.
Anywhoo, here are the pics, enjoy :

If you are wondering what the container is, it's a 9litre bucket cut about 1/3 of the way from the bottom with holes pierced for the water to escape. Also, on the bottom, a thin layer of gravel I found outside for better drainage

edit:I currently have ~100w of light at the moment, 40w being 6400k, the rest 2700k.
