Each of the three seeds were planted on different times:
CBD Auto Blackberry Kush was planted early April (way too early for Automatics on window sill - would not do that again but I was impatient :) )
CBD Auto Compassion Lime was planted late April. (suboptimal)
CBD Auto White Widow was planted around mid May (which seems to be the best time due to maximum strength of sunlight for the whole growth cycle)
The windows are oriented south-southwest with up to 5 hours of direct sunlight per day.
All three plants grew in 8 Liter pots with fresh soil (for tomatos) - there was NO fertilizer added during the whole grow.
