Hi guys, Just started my first RDWC 5 days ago, and ive got 8 XXX Bubba Kush rooted clones growing in an 8 pot DIY undercurrent system. Im running Current Culture's, Cultured Solutions(UC roots and VEG A/B) and following their nutrient schedule. Im using a new RO system with water at no more than 3 ppm. 2 600 watt HPS, ppm at 150 , ph 6.o, my lights are 3 feet from the plants and have been running 22/2 . Everything is finally in working order i'd say. Im seeing a slight wilt in my plants and maybe perhaps a little yellowing, Im not sure the top parts of plants are just really light green (which are about 6 in. high right now). Id say i already know the cause of the problem, I ran the system for the first 4 days without a chiller and my water temps couldve reached a max temp of 85 F (EEEEK) . Ive got my system chilled now and the water is at 68 deg. Roots have finally reached the bottom of the net pots and are peeking through, but ive noticed a small amount of white powder at the base of my stems on the rapid rooter. (along with the wilting and yellowing which i assumed was purely because of the water temps) I was sure my plants would pull through once i brought the chiller in but now im not so sure, I feel foolish for jumping right in but i have to say im excited and thought I could fight the heat with Ice cubes (water bottles) <-- TERRIBLE INFORMATION there i might add.. does not work and its very stressful. Should i Flush with uc roots and RO water? Im not sure what the powder looking stuff is, I was wondering if it couldve been a powder used to root the clone that has just left a sediment. My roots only recently finally reached the water, could it be this is all stress from the roots trying to reach the water level?
