I know its normal but why so soon?

ok well a girl has been put under 12 12 about a week ago and it has come to my attention that there are a few leaves that are turning yellow/drying out/and falling off. I know this is normal toward the middle of flowering but why is this happening so soon?? I dont even see any buds yet here is a few pics

any help is greatly appreciated.

What kind of soil and nutes are you using. Also what is the frequency? I think it could be some nute burn. Is your thermometer reading 69f in that pic?

could be the foil as well.
it reflects heat in diff increments

they want nitrogen. nitrogen keeps them green. feed them some nitrogen.

yea the temp was 69 also I feed nutes once a week they are 4-3-6 for bloom.
and the reflector is mylar.

well if its not nitrogen what else could it be? because they are getting dry and falling off from the bottom up.

spider mites's..or lack of light to the lower leaf's

some kind of a nute d3ficincy,Looks like nitrogen in some of the larger fan leaves, but the smaller ones keeping color and just drying up I would say just Flush the soil well and give her some good blast of GROW without the bloom. some kind of stess I think. maybe even repot and reveg for a while.

hmmm.. what if I just use water through the whole flowering process? wont get much of anything will I? I noticed that the girls were beautiful before I brought nutes into the equation. and I am a first time-er so there is room for error. but yea I think next batch of girls im going to pick one special one that will only get water and see how well she does compared to the others. meh we shall see.
