Well i did it... I changed the water, making sure it's the correct PH balance. I did full strength this time, as the instructions on the bottle says. My schedule is lights on @ 6pm and lights off at 10am. I did the solution change at 6pm exactly and I checked today and WOW. I can tell a drastic change just overnight! I knew I should have taken a picture last night so you can all see, but the leaves filled out and the smaller/newer leaves grew even more than they were last night! When I pulled that basket out of the 5 gallon bucket you all should have seen my expression, LOL. That root was huge! (more long than thick). I think next time, after harvest, i'm going to change my setup to a clear 5 gallon bucket so I can constantly watch the water level. This black bucket makes it difficult to keep track of the water level, that's why you brought it to my attention that the plant seems to be literally swimming. I try to keep the water level just 1/4 of an inch below the rockwool cube.

I'm glad I gradually stepped up the nutes as I did, I don't think things would have gone so well if I didn't. I'll take some pictures tonight and post them so you all can see what i'm talking about.

Thanks everyone for your input/feedback, it is GREATLY appreciated.
