Have you referenced a leaf chart? Seems reminiscent of Sulpher Def. Prob best to start a dairy and upload the grow so others can have a better understanding. https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg

Maui Waui CA deficiency?Can anyone confirm or guess at the kind of deficiency my plant is having? I am not sure if "hard water" (instead of RO so far) is the right answer or if I need some special sauce... Thank you!

Deficiency?My current grow is on its 5th week of flower and many lower leaves on each plant have begun to yellow then develop brown spots. I’ve did a little bit of research and I think it could be a nitrogen deficiency. Any help is appreciated.
