Looking good, 28"-32" is about where I start mine as well, and begin to lower as they get deeper into veg and/or flower. Keep in mind that she will need a bigger dose of Calmag due to the intensity of autocob and length of time the autocob is on (18-24 hours on entire grow) versus a photoperiod plant (12 hours on during flowering). Most general veg nutes have some Calmag in there, but she may require more. Something to keep an eye on down the road. Riding along if it is OK with you, good luck!
