OK, here's my setup:
I've got a 6 trough NFT system with a 35-40 gallon resevior. Each trough holds 4 plants. I'm using 2 1000W HPS Hortilux lights in Vertazontal reflectors.
Here's the deal:
My plants have been flowering for 4 weeks. About 3 days ago, I noticed that the first plant in the far left trough had wilted and was basically dead. At the time I attributed it to insufficient light, because it was kind of a runt and had been overgrown by larger neighbors to the point that it was no longer getting direct light. I thought, "No big deal" and pulled the plant. As I was preparing it (hey, might as well get whatever was on it, right?), I noticed that the roots were slightly darker than normal and came apart rather easily, but they were not slimy or anything. Again, I didn't think much of it at the time.
However, now the other 2 plants in that same trough (it only had three to begin with) are wilting, and they are getting direct light. Furthermore, I noticed that another plant in the first spot of a different trough is also beginning to wilt.
There is nothing wrong with the PH or nutrient PPM.
I do have fungus knats, but they were not a problem last time.
I did add two more air pumps to the setup this time.
What could be going wrong? And, more importantly, how can I fix it before my entire crop goes belly-up?
