Adi Up Member Sep 13, 2009 #1 This is our 5 week old northern light. It has been doing great but I just noticed that several leaves are starting to curl up and the tips are brown. The ph is fine, it is not over watered or too hot. Any suggestions? Thanks Attachments curl-leaf.jpg 83.8 KB · Views: 22
