OK to stop feeding now??

These girls are 78 day old, 43 days flowering (6 weeks) I feed them all full strenght FFTB last night and was thinking this should be the last feeding until harvest (in two weeks). Is it ok to stop feeding now?? Plain water and two flushing from this point on ?? good idea or not?

very nice! Your plants look right on the money.whats the strain?widow?You could easliy start water only about now, or you could wait another week or so by the looks from here and the # of weeks in flowering.Again, great looking plants!

Yeah time to start flushin em out.
Looks great!!!!
