Help panicking about flowering.

I have two plants that I am flowering. Both are bag week so not sure what the type is. The first is a clone of the 2nd plant which was the mama of many clones. I started the 1st plant about 2weeks ahead of the second plants. About a week ago I notice the leaves were really dark and some stems that were turning red on both plants. I decided to just flush the plants with plain water. All was fine the color issue corrected it self and I did not notice any new red stems. Well now on the mama looks thin and sickly especially when compare to her baby. Recently in the last 2 maybe three days the leaves are falling off when slightly touched. i have attached some pics for all to see. The first 4 are all of the thinning out mom. The last two are of its baby.

could just be light conditions and stress from taking cuttings. lots of things really but thats my best guess

did u take clones right before u switched or was it healthy and stress free

I waited for about 2 weeks then sent into flower

i added a couple more light and a t8 and now its seems to be doing better. i am adding nutes again so not sure if it was a light issue or a nute issue or the fact that i took clones 2 week prior.
