Yeah those flowers aren't even close to being done. -a month at the very least because you have to also add time for them to recover. I'd do some pH runoff tests and some slurry tests, as well. What are you growing them in? I've had similar looking problems and it turned out the mix was acidic so the plants looked deficient.....but all I had to do was adjust the pH. It still added on a couple extra weeks for recovery time.
