Iโm not to sure about this strain, the colours look absolute amazing never seen such dark buds. I had 3 fast berry 1 in 5gallon and 2 in 3gallon. The two smaller ones did not grow very well Or produce hardly any buds the pictures do it justice. It must have been due to stress with high temps or overwatering in the plastic pots. The bigger 5gallon produced well and had a good yield.
Awesome job great looking buds! Iโm currently on day 90 and almost ready to chop. I too am having difficulties with early yellowing. It seems these plants are really picky with there environment and food.
