16oz dutch buckets - gorilla cookies

Well we got problems with these girls. Noticed some light deficiencies starting the end of last week and they progressed fast. Yellowing from the bottom of the plants like nitrogen deficiency but their stretch is over so I wouldn't expect them to want much. I increased the feed a little but it didnt seem to help. And after checking everything out I noticed that the cups were staying about 3/4 full of water. So I'm thinking this might be part of the issue. I am working on a setup that might solve this issue but wont be able to get it finished up until tomorrow. Either way, these plants are huge. Crazy how big they can get with such a small amount of roots. I expected issues midflower so everything is right on schedule. The only question is....can they survive? I was going to transplant them and move them outside because I need the space, but I am going to try to push on and see what happens.
