Grow 1 - OG Kush

20230513 - Day 64: Defoliated a few more lower, yellow fan leaves I missed last week. 20230514 - Day 65: 20230515 - Day 66: The buds are definitely starting to get a bit frosty. A lot of the remaining lower fan leaves are turning yellow now. Assuming this is a natural part of the process but I'll continue to monitor them. Added some cal-mag to the nutrient mix since everything I've read suggests this is a good idea. Nutrient water 20230516 - Day 67: Lots of additional yellowing fan leaves lower in the plant. I am now beginning to wonder whether or not this natural vs an indication that something may be off. 20230517 - Day 68: More yellowing and the upper bud sites seem to be fading. I think this may be an indication of a nitrogen deficiency likely caused by nutrient lockout. While I haven't been using a lot of additional nutrients during this process, I am otherwise struggling to come up with a rationale explanation. One area I have been failing to monitor is the pH of my feed and the run-off, so it could be possible I have an issue there. My solution... well for now I flushed her with a gallon of water. I'm hoping that if lockout is the issue then this will be my best bet to try to rectify. Will hold off on any additional feeding for now and will continue to monitor. FLUSH 20230518 - Day 69: Mixed up some super light nutrients with nitrogen last night and confirmed the pH was 6.5 this morning before giving her a bit. Will leave the soil to dry out before any further feeding and will continue to monitor. 20230519 - Day 70: She ended up dropping about a dozen of her lower fan leaves last night that succumbed to the nutrient lockout, but otherwise, it doesn't seem like she's been getting any worse, which is reassuring. I will continue to monitor her closely but am assuming a lot of the other leaves will fall shortly as well. Hopefully the bud sites remain healthy and robust and this whole incident will just result in a smaller yield rather than a total loss.
