Hi all I’ve had a problem controlling the stretch on this strain as you can see. Grown in coco soil with all the canna line as my nutrients. Temps 21 lights on 15 lights off. The plants are currently 3 weeks 2 days into flowering.
I think your light source may be weak or too far away. What are you running? I have a Lemon walker I've run for years she tends to bush out. I flip into flower @ about 3-4 ft finish around 5-6ft under 600w single end hps.
I agree. Also, all that black plastic doesn't help reflectivity either. I would suggest taking the black stuff down and hanging Mylar or the white side of panda film.
