well since your plant is in flowering, most of the energy isnt focusing towards the leaves as much and more towards the budding flowers..its pretty normal

kind of looks like a nute burn in some of the pics as well, try to lighten up on the nutes if your loadin them up...

Looks mostly like lower sets of leaves... I wouldn't worry too much. Give it some fresh water and see if it helps.

Are you using bloom nutes? If so make sure you have enough N
