a majority of my plants now have some yellowing spots on their leaves and seems to be spreading wondering what exactly it is and how to fix it?? attached are pictures of the leaves also have seen dead gnats on leaves directly below lights. Thnks for responses in advance
temps stay around 78 degrees when lights are on and 73 when off, humidity goes from 45-55 % close to the ocean... all in soil
You think I should pull the lights back then or disregard it as not really a big deal an leave as is ?
