So I am seeing a lot of yellowish/brownish fan leaves at the bottom of the plants. They fall off with just a very slight pull or just brushing my fingers through the plant. it is going on with all 4 but happening more with my bigger two. I believe it is a N issue but this is my first grow so I’m not going to pretend that I have the answers so looking for help from you experts.
PS I flipped them to flowering on Oct 6

I’m thinking your yellowing plant is hungry. I’d give that one a full feeding and keep the green one at half. See what happens. I know people here that feed 2000 ppms to their plants every feeding. It should be safe to double the ppm.

That is entirely normal for cannabis to start leaching N from lower fans and discarding them. The N level in your soil is dropping as it’s used by the plant and your supportive nutrients don’t really replace all of the N: most growers feel it’s a bit smoother smoke.

I personally try to support the plant all the way through until the final water only phase before harvest. It makes more sense to me to keep it healthy and happy until harvest.

I heard for the bottom ones it’s normal to turn yellow and fall, but I don’t have a lot of experience.
Your plant looks really good though! Good luck
