Just switched my lights to 12/12 on 3 blueberry kush beauties...thye look great, all over a foot tall, and very bushy since i've been tying them down... I was wondering if anybody had any advice for me going into the transition into flower that I could use to get the most from my girls this harvest. Under a 400w hps, feeding FF Grow Big so far but I have Big Bloom and Tiger Bloom.. Much appreciated!
