I've done some reading about plant problems and even tried the symptom checker but cant quite pi point the problem. I have 2 tote bins (dwc) with 2 plants in each. I just put them in 2 weeks ago (as clones). I have added the recommended nutes as per GH FLORA instructions...ph is 5.8 in both. Out of 4 plants, 1 is growing ok but the upper leaves are very skinny, dark and curling down. The others are amazing. Everything I read points to either over watering (funny for DWC) or nitrogen toxicity but those symptoms to me dont quite fit the problem. Right now I have them set up with bubblers but will only do this for a few weeks. Any ideas? Need more info? Thanks
