nutes question

hey guys,
well i have some questions on nutes.
I just started my 12/12 cycle like 30 minutes ago lol.
im on week 4,
i never used any nutes. BUTTT my package came in
Grow big and tiger bloom.
So my question is, did i miss my oppurtunity to use grow big and tiger bloom? and should i take my babies out 12/12
ORRR just next water add TB and GB with 6.5 ph water?
thx!!

start the tiger bloom, save the grow big.

cool. so starting next watering will be ok then? idk i thought i had to do it a week prior or something

nahhh.......you're golden. don't over-do it. go 1/2 strength and see how it likes it.
