Purpling on leaf? Deficiency?

I am 4-5 weeks into flower with 3 plants. Each of the plants have had about 5-6 large fan leaves that have yellowed and that I have removed (no concern here). On one plant I have noticed 3 leaves that have yellowed and have a purplish colorings. Otherwise the plant looks healthy.
Question whether it is phosphorous deficiency. I have been careful not to over nute the plants and feed weekly but not at full strength.

Thoughts?

No problem.

Stay away from the miracle grow bloom. Use the microbloom or what ever only as needed.

I generally like to run a pretty close to even NPK. Only use bloom boosters if you get a strain that needs it.

Switching to bloom feeds early is what causes a lot of yellowing and other colors.

It shouldn't hurt it. Just don't go heavy on it again.
