2BirdsStonedAtOnce I’m no expert, but my two guesses would be 1) showing signs of overwatering, which in dwc would mean that the air roots are suffocating. I’m not sure if this is your problem, but make sure when you fill the bucket that you leave about an inch of room between the top of the water level and the bottom of your net cup. Guess 2) is a typical nitrogen deficiency but I’m leaning more towards your problem being #1. Without any other information it makes diagnosing hard. Good luck my friend and don’t stress, there’s still tons of time for that plant to bounce back, especially in dwc 🤙🍁

the neighbor I’ve got about two inches of air space and running a commercial air pump with 4 in stones
