I would definitely check the ph, might be acidic and causing the burn. If it gets worse you might want to mix up a new batch off reservoir water with less nutes and flush the roots with fresh distilled water. I just went through that same problem with my plants.hey dude,just trying to establish contacts to help me grow my own weed. im currently running a20l hydro nft tank with a 600w hps, im having some problems but trying to work them out. growing in the closet which is 7ft wide by1,1/2ft deep. when i bought my nft tank, the guy in the show said i would have to keep the pump running all the time as the pump constantly distributes the nutrients over the roots. should the pump be running all the time as i seem to be getting nute burn?!
