Blackberry x3 300W COB

Started back up with another FastBuds strain. This time around it'll be Blackberry strain hoping to do well on this. Prepped soil with added perlite and coco coir. Also mixed in some dolomite lime to boost CalMag for these autos. My fist attempt at growing an auto had CalMag deficiency. Soaked seeds overnight and placed into root riots. Within the next day 3 of 3 sprouted. Few days later, they have been transferred to 5 gallon fabric pots. Mist them with plain water during the first week to keep humid a little higher. Sometime next week, low dose of nutrients will be introduced. Low stress training will also be applied to them. I though about using a scrog technique but I think I'll keep it simple this time.
