Hey if you ever check on this thread again let me add one thing:
Using only 2700k's during flower will encourage that stretch we all hate.
Mix it up with one or two 6500k's to promote the density we all love.
I hope you keep at it, that looked great!
Also I heard someone say if you feed your plant some veg nutes, or maybe 50/50 veg/bloom during the first couple weeks, that the stretch will be miniscule.
But it's your grow, good job!
