Using the bloom switch too now. Most of them stopped growing which is good cause my light won't go higher, the diesel however hasn't got the memo yet and requires special attention every day to not burn.
Lesson learnt: don't put heavily sativa dominant strains in the tent that go for ~13 weeks, I should only use ~10 week strains
Growing same strain, I believe i got the wrong seeds as they all came purple however mine is close to 3 FT with stress training and Fat Colas and nugs! There were supposed to be Auto Kryptonite
