Changing nutrients over?

Yo haría un riego solo agua controlando ph y tds, y ya empezaría con los nuevos nutrientes.

I normally do a sort of mini flush. Then I’ll switch over and feed as you should. Have done it a few times myself till I found what worked for me. Hope it helps

It's totally fine to use whatever in a sense. You just have to take into consideration the whole big picture. What does my plant need for this phase? Research helps quite a bit and yes as larimar said lower dosing or using half recommended levels can go a long way. Hope this helps and happy growing.

Just changing the Nutrients is the only thing you have to do. And to be sure take a lower dosage from the " new" nutrients as recommended , just to be sure not to harm them.

hola buenas,puedes cambiar directamente,alternarlos, como quieras,mientras hagas un control de los dos juntos es lo mismo la manera,hay quien junta 3 y hasta 4 marcas diferentes,espero te sirva de ayuda,saludos y suerte ✋💪
