2 plants have begun "wilting"
 

Hello Ron,

First thanks for this site, After doing much "lurking" I decided to build the 11 plant system, and the thing has worked wonderfully..

The plants are in day 24 of vegetative growth and have looked perfect.... until I noticed last night that 2 plants have begun "wilting" new fan leaves are "drooping". this is occurring on new growth and there has been absolutely no change in color, i.e. there are still deep green, I have searched all of the grow guides and message boards on the net and have not been able to find any causes, I have heard that "Under watering" may be the culprit, but I water 6 times a day for 10 mins and the other 9 plants look perfect.... Here is my system.. once again thanks for this site Ron and this board, it has helped me a great deal..

6 times a day might not be enough. I flood my garden every 30 minutes.
You will find at times that some plants will just wilt and die. Caused by damping off of the plant stem right above the root ball, cutting all the capillaries to the plant and killing it. It doesn't happen often but when it does the plant can't be saved. If a plant looks like it's about to wilt and die then I would clone it to keep the strain going.
