But when you open them up, this is what you see

These are from my lavender

and these are from my Kandy Kush

The Kandy has just started to flower and the lav has been flowering for about 2 1/2 weeks. I just started giving them daja bloom (half) but they have been on a steady stream of
nutes and tea. but i have been fighting the yellowing for approx a month now. it started with just my lower fan leaves, but after the daja bloom it has gone to the inside only.
i know it's hard to tell with just pics and the little bit of information i have, but does any one know what this looks like? the ph of the ground is about 6.5 to 7. and i started giving them extra nitrogen about 3 weeks ago and they shot up and started to look like they were pulling out of it, but then they started yellowing on the inside, like i said.
Any help would be greatly appreciated.

Looks fairly normal, clean that stuff out, no light gets in there and the plant will try and fix it wasting energy. Also in flower the plants use Potassium and Phosphorus like a mofo, nitrogen is for plant growth.

Thanks for the advice...
Even though i clean out all the dead leaves, they are back in a day or two. is that normal? Sorry, this is my first grow and i've made it this far, and just don't want to screw it all up.
i stopped the nitrogen a few weeks back, but i'll take a look at the mofo.
