Pepper plants not growing well.
this is my first time planting peppers and some of them are not doing well. They are mostly hot and sweet banana papers. They are in containers (12" black nursery pots), half of them are growing well (very thick plants and bearing frut) the other half are not growing many leaves and loosing the leaves on the bottom half of the plant. I heard this could be due to over watering the plants but I water them all the same
and half are doing great.
I think the issue could be the soil. I used organic choice MG for some and left over bulk cheap soil on the rest. I am fertilizing with organic fish fertilizers and a 6-10-10 mix at different times of coarse.
Any ideas as to how to get them to grow stronger and fuller leaves? I ask because they are only producing about one fruit each, I think because there are only leaves on the top 1/4 of the plant.
