I am a first time grower, and I started with 2 auto flower strains (Alaskian thunderfuck and Berry Ryder). My Alaskian thunderfuck is growing great. However, my berry ryder stopped growing at 5inches tall. I am on week 12, and it has not grown at all. It grows fresh leaves, looks and smells great. Just does not grow. What should I do? They are in 5 gallon cloth pots, and I am currently on a 12/12 cycle. I run Leds with both veg and bloom lights on. Could someone direct me on how to correct this or if I should cut my losses, please! 😔
