Dude in all reality, your plant could turn dirt brown on the very last day of flowering and straight up be fine. When that shit happened to me on my first few grows i figured out it was because i was giving them way to much light. like intensity wise, not exposure. My thought is, if the actual bud is in good health, then all is well.
ppm conparied to EC just depends on what scale you are on. However I do agree with 1800ppm being to high. I have been seeing that plants like the lighter side of feeding, around 1.5ec. You can go higher but I think thats the most efficient. I also agree with crash about starting to lower it because they are getting to the end of there cycle. The last week if not 2 weeks should be just clean water so you can get a clean burn when you smoke.
ph is @ 6.1 ppm is up to 1500 now, and my leaves are still yellowing and dying, yellowing leaves are starting to appear on the bud leaves now also. not sure what to do. Gonna try and flush and put them on just plain water.
23 more days till 8 weeks, tricombs look cloudy. Think I may bypass flushing and harvest this plant or at least the buds that are cloudy..
How long do they stay cloudy until they start to turn amber?
