First time | ILGM Agent orange

Nothing too crazy happened this week. I've done a little defoliation of the massive fan leaves as the LST was putting some leaves in the dirt. I bumped up the bloom big to full strength as well as the cal-mag. I've still been reluctant to use the FF Grow big as the soil should still have plenty of nutes available. Temps are averaging 80F and a range of 65-71% RH, I'm trying to walk down the humidity a little bit and I think in the next week or two I should be ready to switch to flowering. I've noticed some yellowing at the tips and it looks like light bleaching kinda, but not sure, I raised the light (that's still at full strength) about 2 inches to help it stretch out after LST, seems like it's getting there, but still stumpier then I'd like. If playing with the lights doesn't stop the yellowing I'll probably just water with plain PH'd water for a week and see what happens. As always feel free to comment and help a dude out.
