dr who, so you dont see this being an issue
my grow food is

0-0-7
Food is good.
You really don't need to add a Silica. Your about to flip to bloom any way.
Use baking soda for an UP and skip the high K up altogether
As far as waiting.
You will not "see" any recovery in the old growth by waiting. In hydro (or any style),
any visual change will be seen in new growth only.That takes only 3-5 days.....
So, go ahead and flip to bloom if your ready.....The new fresh nutrient will fix any def., etc. faster then you'll see it.
There will be no effective difference in them blooming and recovering or vegging and recovering. It's faster then most understand..
