It def wasn't in the perlite. But, the bible will be here today, hopefully Jorge will be able to tell me what's up.i have no idea what the stuff would be on your roots unless it was something from your nutes or in the perlite, either way I would say give them a few days they will perk up then go ahead and start flowering hopefully they are girls.....
Will do. Thanks.Some hard learned advice for when you setup your waterfarm. I had to constantly lower the ph in the bucket, I figured out it was from the clay pebbles. They are at a ph of 7 and will try to bring the nute solution back to 7. Pre soak the rocks in a PH 5 solution for 24 hours. That should keep things stable. Im soaking mine now for clones that are ready to come out of the Daisy Cloner.
