Thanks Waji, your grow is looking good as well.
Kevo. From my little experience with it, I've found that Nirvana Bubblelicious is very variable- the four seeds I popped were each unique in appearance from day one, as opposed to my four Ice plants which were extremely consistent; It doesn't surprise me that you got a purple pheno. Also, I did find one of my Bubblelicious phenos to be more nute sensitive than my other plants. Thanks for the post, the compliment, and the questions.
Thanks, Relax, glad to have you along. EXCELLENT question, and thank you for reminding me to document it here if I forgot to post it somewhere above. Yes, I did change something else. I've got a total of 12 bulbs in my fixtures, and all were 6500K color temp prior to 12/12. 12 days into 12/12 i switched 8 out of 12 bulbs to 3000K. I left the 6500K's in for the first week to minimize stretch (red light stimulates stem growth in a HUGE way). Also, that was your first post? Welcome aboard!
Thanks for the posts, guys.
