No problem bro! I was wondering, are you using a sub barrel? sub res connected to the float valve in the epicenter is a good way to keep ppms up and help with ph fluctuation. I like to keep my barrel ppm the same as the system with my ph around 5.7-5.8. as you transition into flower those girls will drink close to a gallon a day sometimes more, ph-ing your system several times a day is not good IMO, also pouring nutrients directly into epi without diluting can be harmful in some situations, using a barrel or sub res will free up alot of your time and the plants will be much happier if the water level, ph, and ppm don't fluctuate so drastically.
I would definetly do some pruning of the canopy, you got the right idea there. There is a great thread on ISA pruning at the top of the Under Current threads. Interference leaves should be your biggest concern. anything blocking light from getting to buds just below the main canopy should be removed during weeks 3-4 of flower. Check out desert squirels threads he is the man when it comes to getting the most out of the UC.
Nothing against Quantum9 I'm just not familiar with this farmer. I'm sure they got mad skills!
Yes I am on the east coast! I might be closer than you think ;) 401 for life!
