nutrition questions

How often do you feed your plants in flowering, ive heard that you can feed full strenght evey other water or you could feed evey watering half the strenght and then maybe flush it few times trough out the flowering period. How are you feeding.
for how long can you store your pre blended nutritions in a container? im using canna terra and canna flores.

You don't want to feed unless they need it. That's why there's so many plants burnt up on here and people asking what's wrong.. They will let you know when and what they need.. Loading plants up is the main reason people have to flush.
Not familiar with that brand of nutes, but usually bout a wk if kept in a cool place with no direct light.
