Bottled, premixed nutrients for some reason just seem to attract new growers. I started with GH nutes but has since switched to a dry/granular mix. With the dry nutrients, I can single out the nutrients to help correct deficiencies.
For instance, say you have a plant that really loves the nitrogen. Like more so then any other plants your growing. With those premixed ratios you aren’t able to give the plant just nitrogen. You would have to also give extra phosphorus or potassium since the mixture is already made, thus creating different problems.
With my Jack’s nutrients, I can single out individual elements and cater better to a plants needs. Completely customizable to any type of plant.
And the best part…I use the same mixture from seed to harvest.
