Small yellow stains
Horosho
started grow question 5y ago
Hello colleagues! Would you kindly help me and tell what these yellow stains may be caused by? I think I could set the ph-level too low, so it may be a deficiency of some nutrients, but the plant seems developing normally.

Roberts was faster than me. 😁 Moisture (drops of water) plus light = spots on the leaf So don't panic

Yellow tips
Dont know why but one of the girls is suffering from stress. I think this is the cause for the yellow tips or do you have a other opinion? I did LTS training every two to three days, maybe therefore? A other reason could be light burn. But with a distance of 50cm I dont think so
