Many thanks for your reply. I'm not a total nerd or novice at this. I've grown a couple of Hydro grows that were quite successful. After reading further about "Aeroponics" I decided to give it a try. The first few weeks were phenominal. Growth was rapid and the 5 to 6 inch plants were (and are) very full and healthy looking and then......

....this morning! Ugh! Droops! I will try to be as specific as I can. My PH is, as I speak, 6.1. Water temp is 24 .2C. Humidity in grow tent is 33%. Temperature is 79.2. I'm using the following nutrients; B.C. Boost, B.C. Grow, Thrive Alive B-1 Red, MagiCal and SugarDaddy all according to recommended amounts and I might add that the fan is now "blowing in the wind". I might also add that I have a fishtank aireator adding air to the water supply. The light (400 MH) is approximately 20 inches above the plants. An exhaust fan is running about full speed.

Once again, the plants look incredible, full and green. The stem is what I will try and describe. First of all I need to explain the condition of the rockwool starter cube. It continually changed to a darker green, I believe some sort of algea. It is now almost black in color. I had this before in the Hydro grow. From there, the bottom one inch of the stem is thinner and dryer looking (hard to describe exactly). One of the plants appears to be stringy (seperating) at the bottom inch. That bottom one inch is lighter (not green) than the rest of the stem. Without being able to provide you with a pic I don't believe I can provide you with more of a description. Hope this helps. I would sure hate to lose these great looking gals. (Hopefully girls, they were feminized seeds).
