| Nitrogen deficiency?
What's up everyone. I recently did a friend a favor by taking in his plants, and I'm determined to bring them to better health and make at least one of them yield some bud. Basically, the big plant is about 8 weeks old and the small plant is around 4 weeks old. They are showing signs of yellowing on the oldest growth and it is spreading upwards. The tall, skinny plant has been having the problem the longest and looks so unhealthy that I don't know if it's salvageable. Also, the small plant is wilting which is a new development, any ideas what could be wrong there? Thanks.
