Yellow leaves during flowering

[TWIZZrx]

Is it normal to have yellow leaves at the bottom of the plant during flowering?? Or am I over watering it?? It 13 days into flowering.

Not enough info. or picture to accurately answer but they still need some nitrogen at this stage.

Yes. but not 13 days into flower. You have a nitrogen deficiency by your description but without info like nutes, medium, lights, pictures ect we cant really give you a good answer. Leaves will yellow at the end of flower as it pulls nutrients from the leaves, but that is like a week or two before harvest usually during flushing. Sounds like they need fed.

Well, now. If we're talking autos, 13 days into flowering doesn't necessarily mean 13 days ago was the prime time to flip. If you're plant is further into it's flowering stage than you think, yellow leaves are normal. Do you have any trichomes you can look at to see how long along you might be?
If they're photo, yeah, yellow leaves at 13 days is probably nitrogen.
