This is my first attempt at aeroponics. It's a Clone and Grow 16. I have eight plants started from seed on 1/9 and I just switched to the flowering cycle. All plants are full and lush between 7 and 12 inches. I worked through my stem issue and all are now strong and healthy. My system is a root mister cycled for 60 secs on and approx. 10 minutes off.

Other vitals inside grow tent (4X4): 400 W HPS (400 W MH During veg cycle), exhaust fan with carbon filter, 6" circulating fan, 5 gallon reservoir with fishtank aereator. Current temp inside tent is 76 degrees and humidity is 31%, reservoir temp is 68 degrees and ph is 5.6 and nutrient ppm is measuring 1445.

I'm a real novice (newbie), third grow, first aero (other grows were hydro) and what I know I've learned here or other reading. Do the above "vitals" look OK?

My current problem is the roots. In one of my tubes (4" diameter X 34" long) roots have managed to grow into and thru my drain tube into the reservoir and are now in the nute solution. Any advice on what to do about this?
