This is my first attempt at Aeroponics. I have a 16 pot system and have eight plants (different strains) 32 days from seed. Plants were growing beautifully until two days ago when I noticed one plant was drooping and leaning. After closer observation I noticed that approx. the first inch of the stem (just out of the rockwool) was thinner than the rest of the stem. Color was lighter with some dark spots and it appeared to be (for lack of a better description) dryer or shredding. I noticed that all plants have it to some degree. The rockwool cubes progressively got darker and are now black in color.

I am using a 4 X 4 grow tent under a 400 watt MH approx. 20 inches from the top of the plants. Air temp is 80 degrees and humiduty around 30%. Air is filtered and exhausted outside. A fan is running (just started the fan upon suggestion from another thread. I have an aquarium aireator running air into the reservoir. Nutrients (all per gallon of PH adjusted to 5.8 tap water) are as foloows; B.C. Boost 3 tsp, B.C. Grow 1 1/2 tsp, Thrive Alive B-1 Red 1/2/ tsp, MagiCal 1/2/ tsp and SugarDaddy 2 tsp. PH is currently around 6.1.

Do you have any idea what might be causing my problem? The plant that I first noticed is still drooping and doesn't appear that it's going to survive. The remaining plants still appear to be strong but I've had to support two of them.
