Could be a potassium deficiency.
What nutrients are you giving them during this flowering period.
Now at the same time it really could be nothing. It is normal for some leaves to to start show some deficiencies and then eventually fall off.
As long as a majority of the leaves are doing ok, I wouldn't worry.
Here is some info on nutrients that should help you understand them.
During veg they use more nitrogen
During flowering they use more Phosphorus
There are three main nutrients found in fertilizer, each with its own special benefit. Consequently, there are three main numbers you'll find on a fertilizer bag -- in order: nitrogen, phosphorus and potassium; they're listed in alphabetical order.
Nitrogen is the first number on the fertilizer bag and it just may be the most important. Nitrogen is one of the most common elements and it's critical to all forms of life, especially plants. Nitrogen is what makes plants have healthy green foliage. Too little nitrogen and plants look anemic and lack full leaves. Too much nitrogen in the garden and your plants will be all leaves and stems and no fruit.
The second number on a fertilizer bag stands for phosphorus. Phosphorus is critical in the development of flowers, it's very important in the garden.
The third number on the fertilizer bag represents potassium. Plants that are low in potassium may look weak or thin. Potassium helps the main systems of the plant function together, helps with photosynthesis and controls the exchange of carbon dioxide.
Hope this helps
