Hey sorry Weedhound, I just found this thread. I have noticed that problem in mine where the tops leaves start to curl down and sometimes the edge of the leaves get crispy. It's also usually accompanied by a bunch of yellowing which you don't have so I dunno.

Unfortunately my current grow is starting to take that week 4 turn downhill that the first two did. I don't know what the deal is because my bins drain all the way and my roots are massive compared to last time, but there's a lot of yellowing going on. I am also starting to see the crispiness of the newer leaves around the cola and I'm not sure what that is about. I post a thread called "Third Grow" in the grow logs. I'm currently at day 22. I am going to change the res again tomorrow because its getting slimy. I also think the fungus gnats are back. The problems just don't stop for me! :wtf:
dejayou30 Reviewed by dejayou30 on . Dejayou 30.....Question/Opinion please. Deja....does this look familiar to you? I believe I am having the same root issue that you had so would love your opinion on whether the plants in my photo (not the root pic...just the plant pics) got to looking in your last few grows? At this point I believe the bottom roots are sitting in about 1 inch of solution that doesn't get drawn out.....the exact same thing you were dealing with. Do the symptoms appear similar to yours?
