Nice plants mate. I grow lots of kush..mostly vanilla but pineapple sounds good..I might give it a go. She is growing nicely but I notice some of the fan leaves are running low on spokes. I can see you have adds perlite which helps with the breathing process but your stems look a bit thin... Am I right in saying you havnt got much wind breeding around those baby's? Get another small rotating fan and place facing down on the plants.
