I germinated the seeds with the paper towel method. After 1-2 days the seeds sprouted and I put them in small pots (approx. 0,5 liters) of light soil.
After 14 days I transplanted the seedlings into 11l pots of light mix and started added Biotabs nutrients. Four days later I topped the plants and started with LST. So far the plants seem healthy and vital. Some leafs of the AK had a light tip at around week three of veg. but the new growth seems healthy. I water the plants every 2-3 days with about 10 l water per plant.
I'm afraid that the Z and Z could be a hermie but I'm not 100 % sure yet. I posted a picture of what possibly could be a male pollensack. Maybe some experienced growers can help my out to find out if it is really a male flower?
