Flower day 47 flush help

I am currently running GSC, Silver Kush and Sour Kosher. Today is day 47 from light switch to 12-12. I flushed them with Flora Clean to do the switch to using my ending line of nutrients. Cha Ching, Big Bloom and Tiger Bloom. I noticed that the leaves on all of them have started going yellow. The Sour Kosher and Silver Kush are a bright banana yellow and the GSC just starting to yellow and purple on the fan leaves.

I am a bit worried I made a mistake flushing this early from the switch. Should I start feeding them again immediately or am I good and leave it till next watering?

i am growing in FFOF and am using their entire line up in 5 gallon pots. 8 weeks veg.

thanks for the help
