Close to the end? So he's got a 4 week strain?
What you're seeing sounds like nute burn. Pics would help but there is some amount of leaf-drop that can occur in flowering if you don't feed with enough nitrogen to support the foliage. Usually a nitrogen deficiency starts will yellowing leaves at the bottom and should the deficiency go uncorrected, the whole plant will turn yellow. Anyways, what nutes are you using, how often and what is the NPK value?

Hell yeah. If it takes from seed 5 mths and he has 4-6 weeks left I would say he is getting close to the end of the plants life cycle. Wouldn't you say?

Sorry I see indoors now. I forgot most of yall only veg. a month. Baby girls. I was refering to a hardy outdoor lady. But none-the-less yellowing leaves I have found is not that big of a deal inside or out as long as its not spreading up like nute burn will. Nute burn happens rather quickly though don't you think.

doesnt matter how long you veg when a plant starts to flower it signals that its life cycle is about to end and the buds begin to draw all the nutes it can(mainly nitrogen) from the lower leaves. hence the yellowing then eventually redining and dieing of those leaves. give it a shot of nutes maybe but that color change is normal dont worry.

Pics would help a lot but a few yellow leaves isn't the end of the world. He's also talking about reddish brown leaves though which in my experience comes from feeding too much. Possible salt build up, pH issues, deficiencies or nute lockout, hard to say. IMO, 3 weeks of flowering means 6 weeks left and that is a lot of time for a problem to take hold and really harm a plant. Again, pics would help.

I don't like to diagnose deficiencies over the interwebs because if you take my advice and I'm wrong, I just did you even more damage. I do think you're looking at a deficiency though and based on the fact that you 'havnt fed it nutes in a while', I'd say it's about time you start. I'm a fan of a more balanced fertilizer, maybe a 1-2-1 ratio since you're in flower. What do you already have?
