Dramatically losing leaves at flowering stage.Advices are needed.

As the images shows,after about 4 weeks of flowering stage,my plants are dramatically losing leaves on lower part of the stem.They became yellowish and dropped layer by layer.It seems only small leaves around the flower survive.As as result,almost every big leaf dropped and the plants appear a bit bald especially on its lower part.Is it normal?How to deal with this issue?
P.S. These plant have suffered spider mites for about 1 month and then recovered.I'm not sure if it is relevant.

Thank you very much!

nute burn, whatever you sprayed for mites, ph? hard to say, but that is one sorry looking girl.

(For adminitrators,sorry for putting this thread into the wrong column.)

I am using a kind of biological soap as the pesticide.As its description says,the main ingredient is tallate.Is it OK?

I keep the grow room somewhere else,I will check the ph next time I be there.

Some of my plants do this but it's the way i LST,lower-middle leaves die,but only fan leaves UNDER branches.It's normal for me as it stops at a certain point,my plants simply don't need the extra foliage and are shedding for aeration,It only becomes a problem when all the leaves are doing it.

wow, that is not normal. it is so very rare that i ever see a yellowing leaf in my room even at harvest time.

Maybe feed ur plants but for real u should just kill those things! There not even worth keeping

Not saying it's normal for everyone but it is for me because it stops at a certain point.And at harvest if all leaves are green that means i used to much N
