I'm not trolling, it just looks like it....
Runbho, you forgot to mention that you added more fert to soil that already has fert and in your thread you mention your runoff EC as being well over 2.0. That's just your runoff. There's really no telling right now what's in your soil. When you measure runoff pH and EC, all that tells you is the value of the runoff. It doesn't really let you know what's in your soil. If you're going to make light of what I say, at least be accurate yourself please. If your runoff EC is high, then you probably have too much fert in your soil. But that's all that can be determined.
Sgrey, I considered the possibility that your plants were finishing and turning yellow, which I know is what this plant does as it dies. But what you have going on there isn't what I've see of that process. But I could be wrong. Maybe your plants are nearing the end and this is just normal. Either way, you want to avoid fertilizing as more fert won't make for a good finish now. If there is too much fert, this will get through more weeks like what tpc_mikey is talking about. If your plants finish in two weeks, you don't want to add more anyway. Just water when dry and let them die. If I'm wrong or right, it doesn't matter if the plants finish soon. If they die before they finish the way you want them to, then I was right. I hope this works out for you. I think mikey might be right about having a long flower time than you think. We'll see.
