When's a good time to switch nutrient brands?

[Southerncough]

Greetings gardeners,
I've been running Dynagro 1 part in my garden for the last year or so and am considering switching things up and trying a new brand for a bit, maybe canna, Rx Green, etc but waz wondering when's a good time to switch when in a perpetual harvest setup? I'm running a small ebb flow table under a 315CMH and flipping clones when they're 8" tall, coco in fabric pots but have some new clones in 4x4 rockwool that I'll be flipping in a few days, etc.
Thanks yall!

just a suggestion..

switch nutes between stages or starting fresh from seed / clone. just the way we did it, nothing scientific.

Best time to switch is when you run out of the other shit...lol

Cool, thanks everyone. Just curious when to do in a perpetual grow. It's like doing an oil change while driving your car LOL
