Critical - RQS - first full DWC hydro

Day37: Week 6 is off to a quick start. Dropping the nutrients considerably to around 600ppm/1200ec. Fading is progressing faster than I thought it would, considering adding back some nitrogen on day 37. Buds are looking thick and starting to swell and continue to stack. The smell is sweet lemon followed by notes of coffee and fuel. Smells really amazing. Purchased new pH meter as the cheap $10 amazon one crapped out and can't be having that during week 6/7/8 flower...it arrived today and thank god it did because I prepared 3 gallons of water for top-off and pH adjusted with the cheap meter. Checked it when new meter arrived today and was not adjusted to 6.5 as I was targeting one gallon was measuring 7.1. Cheap pH meters are like playing with fire - almost got burned! Day 39: Looked the plant over really closely for male flowers and nanners, found a few spots. Picked a few spots and trimmed entire small branches where needed. Most of it was under the main canopy. Some of the faded leaves are ready for trimming, I pruned them to prevent decay. Plant is clearly moving towards senescence. As I am seeing the fan leaves still in a somewhat prayer mode in the pm photos, I am wondering if I have enough light for her as I was worried about in prior weeks. Day42: Got some lights off, flash on camera pictures in the morning before the lights turned on and my goodness is it frosty in there!!! Water change in the evening to transition into week 7.
