On day 1 I changed out my reservoir. I lowered my nutes to 650 ppm(25% reduction). I adjusted the PH down to 6.1. My left plant has some burnt tips from either PH shift or over fertilization. My hope is that the lower ppm will help to resolve the issue before it spreads.
On day 2 I adjusted the reservoirs PH from 6.3 to 5.9.
On day 3 the reservoirs PH is 6.0. I installed my new 200 watt HLG Rspec. I adjusted PPFD readings to 700-1300 PPFD on all tops.
On day 4 I adjusted the reservoirs PH from 5.8 to 6.2.
On day 5 I adjusted the reservoirs PH from 6.4 to 6.0. I diluted my nutrients in my reservoir by removing one gallon of nutrients from the rez and and adding 2 gallons of straight tap water to the rez. This brought the nute concentration from 770 ppm to 540 ppm as the plants will be entering the ripening stage in a few days and they have too much nitrogen judging by the extremely dark green leaves and burnt leaf tips on some branches of the left side plant. The buds seem slightly smaller then my last run which may be due to an excess of nitrogen and maybe not enough light as some of my tops are taller then the others making proper PPFD challenging. All in all the girls are coming along nice and I look forward to the final weeks of flowering 😀
On day 6 I adjusted the reservoirs PH from 5.9 to 6.2. I think I have halted the nute burn as I haven't seen it progressing any more on the leaves. I will continue to monitor closely during these final weeks. The trichome production is increasing with some trichs on top of colas starting to go cloudy. The pistils are turning brown with roughly 40-50% are turning brown all signs I'm getting closer to the harvest window 😆. I dimmed my light to give 600-1000 PPFD to tops.
On day 7 I reduced my temps to 75 during the day and 68 at night. I adjusted the PH of the reservoir from 6.6 to 6.1. My reservoirs ppm was too high so I diluted the rez with 2 gal of tap water. This brought it down to 480ppm. The average ppfd to all 14 tops is 604 with no top receiving more than 1000 ppfd
