On one of my current seedlings, two of the real leaves developed a white patch on the leaf edge. Also, a couple of the biggest leaves were beginning to curl and look very dark green in color. None of the other seedlings did this. The seedlings are White Label Northern Lights Feminized. Any ideas on the cause?
Thanks for the reply. However, I just googled pics of powdery mold on leaves, and my problem is different. The white patches on my leaves were sort of like the edge of the leaf turning to ash. Kind of like it was being "eaten up" by a disease.
Could be sun burn or maybe nute burn if they are turning real dark green first might be too much nitrogen. If alot of leaves start to turn yellow now its probably nute burn. Anyway you could post a pic?
