We have been trying verrrrry hard to grow spinach indoors. We are growing kukabura spinach. This is after 4 weeks. The leaves have started to curl and have white/yellow spots on them. We had the aluminum foil in the back to reflect more light which we took out yesterday. One wrong thing we did was to water them at night around 8 PM. The light goes on at 6.00 AM until 10.30 PM . Should we start again and abandon this? The 2 week radish plants also have browning on the edges too. PLEASE HELP
