Often when you flip to flowering they grow rapidly. At this stage yellow tops are common. Extreme yellow would be more of an issue. Will just have to keep watching.

Using just some ordinary miracle gro stuff from the store, nothing special.Hmmm. The times I’ve seen yellow tops it is usually from rapid growth. Bright yellow can mean iron deficiency- but that would usually be at the top of the plant, I think. Iron def would normally be caused by ph being too high, I believe.
I’d just keep an eye on it. If it was all the upper growth it would be more worrisome. Not sure what medium you’re in or if it’s its one where you need to pay attention to PH (?)
Thanks!Plants looking great
Best not to fix what isn’t broken. To me the feeding level looks close to maxed out, judging by the shiny dark green appearance.
6.5-6.7 is the usual ph range for soil I believe. Ph is always tested after nutrients are added to water. But any decent soil should be able to handle a variety of levels So I wouldn’t worry about that much. They look good.
