Humid acid, 30 days into flowering?

Just go some humic acid > humboldt nutrients flavorful. I'm like 29-30 days into bloom, is it too late to add this to my nutrient regiment, will it make a difference this far into bloom? I'm useing humboldt nutrients organic naturals line

I use the same line. I use it all the way to flush, both "Humboldt" and " Flavorful"

Humic acids, along with Fulvic acids, help increase nutrient uptake to the plant.

No it's not to late to add some. Brands with higher concentrations work best.

The use of a liquid Kelp extract at the same time helps even more!
