question about seeds

[ice#1]

have a quick question about sensi's skunk#1 i bred her with one of her brother's to produce seed she was 4 weeks old from the time hairs started it's been about 3 to 4 weeks since at first the fan leaves started to yellow 1 1/2 to 2 weeks ago like useuly do for the time only problem is all the leaves are dieing starting at the tips at first i thought overfeed so i flushed twice since then but it keeps getting worse i have only gave them fox farms big bloom since they started doing this. also i've had this girl for about a year working with the clones and this is the last one till i germ some more seeds and realy want to get as many of the seeds to get ripe but the mom seems to be dieing right before my eyes day by day is this normal for a fully seeded mom to do this before any ripe seeds are formed or will they ripen as she dies

thanks for any advice
