Hi, I'm doing a science experiment using celery seedlings. I was testing how greywater would affect plants. I had all of the seedlings in a sunny area and I gave them 1/2 a cup of soapy water every second day. My control got watered the same amount every second day but with plain water instead. I didn't use any mulch or fertiliser. All of my plants became yellow, including the control, and I'm not sure exactly what could have caused this to happen. Was it that I was giving them too little water or that they had a lack of nutrients, or could it have been something else?
