Purple Kush & LSD

I don't know what to make of the purple kush right now. I'm going on 6 weeks of flower and it's got tiny buds. I had a hint of potassium deficiency about a week ago, but I've been feeding heavy and they are very happy. I've heard there are three phenotypes, and I believe I got the one which will show no purple with tiny buds. The purple kush smells like wet shoes. I'm not really happy with the plant right now. I hope it smokes nicely, but so far the plant is a bust. Not impressed Kannabia. NO HINT of purple at 6 week mark. I think it's going to take 80 days+ to complete. I'm almost positive the other plant is an Afghani #1 now, because it's so stretched which is common in the strain. It also smells like coffee which is a sign growers have mentioned on the Sensi forum. It also seems like I got another slow bloomer in this phenotype, but it's putting out twice the bud of the purple kush. I think I have 4-6 weeks left before completion. MUCH slower than my first grow.
