HELP! my girls are sick

I'm noticing that the plants have almost no leaves. I'm also noticing that the leaf in the last pic appears more than healthy enough to have stayed on the plant. Chopping all of the healthy fan leaves off is bad for the flowering plant and may be causing problems.

 

idk about this specific strain, but many finish in 8 weeks. It's natural to see yellowing and dropping leaves late in flower.

 

Whatever is left of the leaves
is P deficient.

Try upping the nutes a bit.

I wouldnt start making all sorts of changes
now. Shes come this far.

You don't appear to have any obvious, major problems. Give them more food as Freak suggested and just continue refining your growing technique. Keep track of the pH readings of both the soil and the liquids you water/feed with. Monitor the temps at canopy level. Provide sufficient cooling for your lights so you can bring the plants as close as possible.

Above all, avoid cutting the plants during flowering. The leaves absorb light energy to grow buds with. You should start by only cutting leaves blocking light from getting to one of the stalks' tops, and then only in the first half of flowering.
