Brown spots on leaves II. This is my first time using the forum, so I have minor problems responding to your opinions 😂. First of all, I would like to thank everyone for your answers and your time. Now I get to the point. The plants have quite good conditions in terms of temperatures, humidity, CO2 and light. Daytime conditions: temp 26-27, humidity 60-70%, co2 800-1000ppm, lights 500-600. Night: temp: 21-22, humidity 50%, co2 500-600ppm. I will now attach more pictures that may help with the answer. Coco with perlite, ph 6.0 ec 1.0-1.2 pre buffered coco.
