Flushed and drained the rez completely this evening and added back a pH'd straight rain-water and Final Phase solution (2.5 tsp per gallon). The Final Phase actually increased the ppms to about 100 which is fine - it will use this for 1 day and tomorrow night I'll do the exact same thing, draining the rez and adding back a fresh pH'd rain-water and Final Phase solution. The root-mass has obviously absorbed enough nutrient that it's difficult to bring the rez ppm's down
all the way, but I'm pretty close. After rotating the solution for about a half-hour and then testing, the rez was at about 200 ppm. Considering the Final Phase increased the ppms by about 70 ppms, we were left with approx 130 ppms. After tomorrows identical flush, I hope to be down to ~100 ppms or lower, which will likely be the final test before chop time Friday evening.
So I unplugged my light this evening as well - by Friday evening at 7 pm, it will have had about 43 hours of darkness. I can't imagine I'll see much
more difference in size of the tops at this point, but wow they're already looking fantastic. At this point, I'm hoping this last flush will pull out any left-over nutes from the buds. I tasted a few leaves from various parts of the plant, and couldn't taste any bitterness...to me, that's a good sign that the plant is already quite 'clean', but this flushing will be a good closing touch, hopefully giving an even whiter burning and tastier bud.
Things are looking up - just over the horizon, the finish line is ACTUALLY in sight!!
Stay tuned for more updates this week and plenty of pictures of chop-to-trim-to-hang-to jar!!!
