Hello. I grow hydroponically in a greenhouse. I have a ridge gourd plant. It started fine but now the leaves are getting spots, discolouration and drying. I was wondering if it is because I had sprayed them with neem oil but I don't think that is it. They are under a white grow light for 5-6 hours daily. The other plants (two bottle gourd) and two dill plants are doing fine. They are separated, fans are operating all the time, and temperature of 68 degrees. The plants are growing in perlite in a bato bucket. Photos attached. Thank you very much.
