I am using the bio canna and bio terra line. Blueberry from dutch passion. after germinating they spent one week under flourescents. Then did 5 days under a 600 watt. After the 5 days I then put them under my 1000 watt. they have been in 18/6 for two weeks now and they are still very small and halve only popped one top!! I thought by now they would be around 12-18 inches in height at this point. they are not over watered, they are not over ferted. I am using reversed osmosis water tho (if that makes a difference or not). Please help because the growth that is there is healthy...any feed back would be appreciated....
