This is one of those things that many growers have mixed feelings about so really whatever you feel comfortable doing.>>>>

I don't know about that, everyone I've read says not to touch sun leaves until they die.

Pruning and trimming sun leaves are two different things.
Purple Daddy Reviewed by Purple Daddy on . Trimming 3-4 weeks into flowering? Hey everyone, I was going to post this in "Plant Problems" but everyone over there has spider-mites, and I didn't want to catch them. I've got two pre-98s and one lav just over three weeks into flowering. The sepals (to a lesser extent) and the adjacent fan leaves (to a greater extent) are blocking the light to the tops of each branch. Would it be ok to cut these back a little bit like I would for a newly cut clone? Can I do more, less? Any suggestions would be appreciated. Rating: 5
