Sour Diesel Auto

Week 3! First plant is growing like crazy so I did a little experiment and topped the previously topped sites for a second time, and yes I know topping isn't good for auto's but she was growing vigorously so I believe she can handle it...time will tell. 2nd plant is severely stunted from the first topping at day 12, so I left her alone and will let her catch up. She clearly has some sort of deficiency IDK what yet but Im not worried..early stages of veg I'm sure she will grow out of it. First line up of nutrients, a little cal mag, full recommended dose of 3 teaspoons big bloom for seedlings and a 1/2 teaspoon of grow big.
