CORRECTION: the PH of my solution in res is 5.5, my RO water is at 6.7... sorry for the confusion.

change solution every 2-3 weeks. They eat about 2 gallons every 4 days so i replenish with a 3/4 solution.

I run the heavy duty commericial air pumps so areation is no problem.

I have other buckets running the same nutrient solution and are the same size with no current problems. all of which are at 600-750ppm.

roots are in healthy condition, trust me I have seen some bad root rot before.

Wilt to Sudden death I am in DWC with plenty of air in the buckets, 4th week of flower, 1000W HPS, using GH nutes, PH stable at 5.4-5.7, nutes ranging from 600-700ppm, temp is 75-84 day, RH = 49-56%. Two days ago I notice the water level has not gone down like the other buckets which eat about a 1/4 gal per day and checked to make sure all the nutes and PH was correct. Everything checked out fine. Today all the leaves are drooping to an extreme measure as if the plant has stopped all water/nute takeup. the Rating: 5
