Hello, My White-Widow Auto is in week 4 (first grow ever) now and started getting the symptoms about a week ago. I had the LED about 30cm above the plant and raised it to 60cm now. I think it stopped the plant to get more yellow spots. But now it started rolling the leaves like on the picture. My PH level is about 6.8. any suggestions? Thanks a lot in advance. My specs: HomeLab40 180W Grow LED Plagron Grow-mix Temp: 25-28° Celsius Hum: 50-60% Fan for Air circulation
