I hope we get some more experienced people to answer, because I am starting to have a similar problem with the roots of one plant. So, I bought another air pump and air stone today. Too early to say if that fixed my problem, but that might be be a possible answer to your problem The only other thing I noticed in your case is that at 25 days, I think you should probably have your plants using full strength nutes or close to it. You may want to jump to 1/2 strength next feeding and full strength after that if you don't have any problems. But I'd like to hear from some more experienced growers...

Anyone?

well the plants have been looking great and have not been showing any signs of deficency, next res change i will probably up the strenth
