5th week ov flowering and leaves falling

i am in my 5th week of flowering and some of the bottom leaves are falling off. some of them are healthy and the are still coming off and there are also dead leaves falling off is this ok

this can be normal as long as its not happening in excess. when a mj plant is nearing its end of the life cycle it will start yellowing and dropping leaves.

but alot of the leaves that are falling off are green

ok thats not good. do you have any pictures?

no but i can explain perfectly. the bottom ones seem to just drop off when i touch them like they are hardly hanging on all the top leaves are strong no problems there but the bottom ones are jus falling off some are dead i can tell like witherd away but a few are just normal healthy green leaves other than that there are no problems buds are showing great and plants are all healthy

i starting to think its a K deficiency, have you fed at all?

thx 4 da help
