The biggest limit on good prouction in containers is containers that are too small. It leads to inconsistent soil moisture levels, nutrient deficiencies, BER and blossom drop. Additionally trying to use only organic nutrient supplements in containers is a challenge since there is no soil food web in the container to pre-digest them to a form usable by the plants.

The way to get around that problem is to use organic liquid supplements and use them frequently and regularly. Nutrients wash out of the container every time you water so they have to be replaced.

There are any number of good liquid organics available but to cover all the primary and secondary micro nutrients you usually have to use 2-3 separate products. For example many will use fish emulsion for the nitrogen and phosphorous needs and add one of the seaweed emulsions to cover the potassium and micronutrients.

Check out the many products offered by Planet Natural and EarthJuice to see many of the products available.

But you are growing big indeterminate plants so unless you are using 15-20+ gallon containers for them getting good production will be a challange.
