I wouldn't worry about using a veg nutrient during the transition phase. I've always switched to the bloom and never had a problem. The only difference between veg and grow is the NPK and most bloom has enough N to sustain the veg growth needed in the transition period.
Otherwise, very excited to see your progress. Please keep this thread updated!
Also, why are you deciding to go with such a low yield strain? Why not something with a little more girth? Is it a market requirement (I've felt that pain)?

very interesting.
I dont know if I mentioned yet but I am a complete noob. This is my first go at it myself. The guy who introduced me to growing always did a 24-36 hour darkness period before flip. He told me it was to reset the internal clock of the plant and get it ready for the change in photoperiod.
Now that you mention that reducing this dark perior will actual aid in stretch, it kinda makes sense to me.
So if I decide to grow this cut again I should just flip to 12/12 with say only 6-12 hours darkness?
