First time using nutes

I bought big bloom and tiger bloom. When you mixed it ,you HAVE to use the whole gallon? Will it get bad?

I use MG soil. Nutes Full strength or or not?

it will keep fine, start at 1/4 or 1/8 strength. mg soils come with nutes added usually. give us more info like how old your plant is.

1 month veg 1 month flower= 2 months

good, that means it probally ate up most/all of the nutes so you dont have to worry about burning em quite as much. use 1/8 strength at first so it doesnt burn em and gradually increase the strength over time. it cant handle 1/2 or full strength nutes yet.

1/8 is fairly weak. Actually very weak. I start with 1/4 and work up from there depending on their reaction. You're gonna want a higher P than N nut system now as well since youre vegging

thanks peeps
