Hi Prof, I think it could be one of two likely, and opposing, issues.. From the last couple of pic updates, it looks like the youngsters are/were having trouble with either pH or nute overload-from your soil being hot out of the sack. If its that, then they appear to be trying to deal with the big nute hit. Now, the opposing possibility is that the soil ISN'T hot, or the girls have used up what they could, and now they're hungry, which can show signs as the pics depict. This is a tough one, because fixing one of the possibilities will make the other worse.. If you did give them a decent flush, you'll want to finish it with 1/4 strength nutes, so the soil isn't empty, so that might be the more prudent route. That way, if its too much nutes, you'll flush the majority and have a light dose remaining, which will mellow the nute overload. And, if its too little nutes, then you'll have 1/4 strength added, and they should respond to that nute infusion positively. That's what I would do, in the same situation. Best to you.
