(organic) ferts to use to make plant stems bigger in outdoor growing

Try Hygrozyme. I have never used it myself but I hear it does wonders so, I did just order it. Also try bat guano and bone meal for natural ferts. What kind of grow medium are you using?

Any wind in your area? The stronger the breeze, the stronger ther trees.

Eight plants in one five gallon pot?

You'll get buds, whether one plant or eight.

I would watch for flowers, and as soon as you reach two confirmed females, remove the rest of the plants. JMHO

The plants in the ground will benefit from a heavy mulch. Worms and bacteria will break the mulch down into soluble organic nutes.

Blood meal, bone meal, fish and seaweed emulsions, wood ashes and compost will provide a rich environment for your plants.

Here is a site that can give you more details.

I used organic gardening methods for a couple decades. I was eventually convinced that moderate amounts of chemical fertilizers are appropriate in a nute mixture that includes organic nutrients.

The chemical fertilizers are usually analyzed precisely for content, unlike home made mixtures.

The chemical nutes are insurance against depletion of highly soluble nutrients like Nitrogen and Magnesium.

there is a litte breeze but not much and in the smart pot i am using dr earths potting soil and in the ground i mixed the soil in the grow area with some compost i got from lowes

Give your plants a hard shake from the base of the stem each time you tend to them, to will make them stronger. An organic additive for the soil could be some egg shells, for calcium, or you could buy cal-mag, you probably need more nitrogen also.
