Everything is going well. Changed the reservoir and top off tank. Reservoir is at 900 and top off tank around 400. I cut back on the Grow, since I realized the Micro and Bloom have nitrogen, and that should be more than enough at this stage of flowering. Made up the difference with more Bloom and Big Bud to get up to target ppms.
The buds have been fattening up nicely, so I am hoping the end game is near. The CP is now entering week 6 of flower and the GG week 5. According to The AN feeding schedule, I should be switching to AN Overdrive for the last two weeks of flower before a week of flushing with AN Flawless Finish. At some point, I am going to have to figure out when to switch from Big Bud to Overdrive, based on when I think I am two weeks away.
Based on everything I read about GG4 photos (which is how I am treating this plant), flowering could last for 8-9 weeks. The CP is still ahead of the GG4, but I have decided to make the GG4 schedule the greater priority. Why? I think the GG4 has a chance to bring a very good haul, and I want to maximize the yield and quality. Hopefully, the CP hangs on there well. If it goes a week too long, I hope all that means is the indica effects are just a bit stronger as a result.
My ph pen has been acting up for the last couple weeks, and is now hard to get a stable reading. Instead of buying another cheaper one like it, I am investing in a Bluelab Guardian Connect for this and future grows. (Thanks for the recommendation, MOG) In addition constant display ph and ppm, this model logs the EC/PPM, PH, and I can access the logs via wifi and set an alarm when they are out of min/max range. This is the final step for peace of mind, when I have to travel.
