I think I agree with this.To my eye, this is deep breath and wait to see how the plan is doing territory. They look good enough to me, by which I mean i kinda feel like when i am editing a piece of writing and not sure if I am making it better or not.
Just my two cents. Unless they take a turn down, I'd wait until they have their feet under them from LST.
Others may say I'm blind, an idiot, etc. And they would probs be right. Idk.
I know with organics and soil, you're trying to amend preemptively as apposed to address acutely.. but I think in this case, the moisture content/aeration is probably going to be your bigger factor.
I also might be duncing out here...
edit: to add to my (maybe duncish) thought.
I'd think because of your cooler temps, you might not have the soil evaporating so quickly, and the plants might not be transpiring so quickly. And, because of the recent LST, they're probably not taking things up so quickly, but rather reallocating their resources.
