little update: ... I vegged my 'Daddys Girl' for exactly 8 weeks, and switched to my 12/12 flowering cycle 7 days ago ... I'm getting the pH settled, getting more predictable for me, now, and the GH nutes seem to be doing fine ... my temps are great, but my humidity is high ... that will be fixed when I install my new vent (courtesy of xcrispi, thank you :thumbsup: ) ... I FIM'd her after the 5th internodes, and she responded with 3 growing tips, my 3-headed monster :wtf: ... in short, I am surprised at the rapid growth, it is even better than I would have suspected ... if this plant hadn't been light-bleached as a seedling, and almost died, I might be afraid to open the cabinet door ... the CFL in the photo is one of those odor-neutralizing bulbs, red-spectrum, and they work well ... thanks for everyone's help, I'd be lost without it ... :jointsmile:
