Yellow Leaves and skinny Girls

[TopThumb]

Been noticing more than normal(at least for me) yellow leaves. My girls have flowered and buds are growing so I expect some leaves to turn but not this many I'm getting about 6 to 8 per day. Could there be a problem? Also, this is my 3rd year of growing outside and this year the plants seem to be what I call skinny, not bushy like the previous years. These are Shishkaberry clones. I'm using the same dirt(fresh), watering schedules and nutrients that I have before. Here are a couple pics showing the yellow leaves and the other showing how skinny they are

Too shady?

Could be, they get about 8-10 hours of sun a day.

Are you growing in the same spot as the other grows? Tall skinny female plants can be lack of sun (often too close to other plants so they compete to outgrow each other) and/or lack of breeze.

Looks pretty normal for its stage of growth but I'd want full sun all day if you can

They are in the same spot as other years were. I can say that in the last 3 weeks we have been covering them(just above) to keep them dry because of unexpected rains. We are using clear plastic so it's not blocking all light. Another thought is we have had a lot of smoke here in the last month from nearby forest fires(we're in Oregon).
I forgot to add that as for breeze we get like 5mph breezes sometime up to 10mph so much so I was thinking about putting up a barrier to block the wind.
