Waka, I also have mac1 and it will put on weight around 10-11 weeks so wait a little longer till you harvest her and she will produce more with your light.
Thanks for that bit of info! I normally run 8-9 week strains so I took it to be inline with them. I run 600w of HLG LED's in an 8x4 and pull 2-3oz a plant and I got about 40grams off the MAC1. I'm going to up it to 800watts and bring it to 11-12 weeks next run. Thanks everyone!
