Landrace cannabis growing question

[Newbill10]

How much Nitrogen is needed in flower for some Cannabis (landrace Sativa) plants? My experience with cannabis tells me it is easy to overtax flowering plants with nitrogen. Other stains in the same soil are fine.

I re-potted into fresh soil Mid August. Started adding extra fish fertilizer for yellow fan leaves.

Today they look like they need 7 more weeks in flower, the plants are 11 feet tall.

I'm still getting a lot of yellowing fan leaves. Should I continue the Nitrogen at 6-7 weeks into flower?

I concur if you are growing "land race" cannabis which really does not exist being all cannabis has had some level of human intervention if the native soil is low in nitrogen like a lot of sativa varieties then to much can really screw them up.

logic would say they need more fert,, unless the fan leaves are showing burnt tips. but so many other factors at work here. i say more fert till leaf tips say not to.

i battle yellowing leaves constantly,, so i know exactly how to fix it,, haha

i'd be willing to wager that there is still some pure cannabis strain out there somewhere, as yet undisturbed,, and karma sent it stays that way,,
