These girls are looking great. I lowered the lights down right on them. Don't forget that the bottom half of there soil is 80% coco coir and 20% perlite... I am pretty much treating them like a coco grow at this point so they are getting nutrients every day. Buds are going to swell quick, bet they will double in size in the next week.
I have a few rust spots on the leafs but that's normal for Incredible Bulk Autos in flower. I have added some Sensi Cal-Mag Extra to help and raised the ppm to 420-450.
I had to bend the tall Sativa girl over because she grew too tall. She recovered without issues.
