Fox Farm Big Bloom late in flowering?

I'm like six weeks into flowering and I haven't been able to afford any good nutes until now, I was thinking of ordering a quart of Fox Farms Big Bloom, is it okay to start giving the plants it so late in flowering? I want the buds as large as possible.

Thanks.

Also does anyone know a good site for buying nutes? All the ones I see it costs like $10 just to ship a quart of Fox Farms.. insane.

i would say go to the fox farm site type in your zip code and find a store near you that sells what you want. hopefully like me you get lucky and find a nursery less then 10 dollars wroth of gas lol

introducing nutes is good at any time other than to seedlings. but i would recconmend a week of fresh ph balanced water to flush the chemical taste outa your buds befor havesting!!!!!!!!!!
