I would say it's more than ferts, soil also plays a roll. This year I changed soil and ferts which produced a much healthier bushier Bhut plant. Some don't like MG some do, others have their own mixes. I used MG orchid mix filled 1/2 the pot then added bone meal mixed in, took a mix of MG organic potting soil and the orchid mix and filled the rest then put my seedling into the pot. I then used a fish emulsion fert, used Epsom salt, and a liquid feed of MG not all at once of course.

I do containers as well. This year I did a mix to see what works best. 6 in ProMix BX, 6 in Espoma Organic and 6 in MG Organic. The ProMix has the best water retention by far, the MG the least. As far as ferts I used fish & kelp emulsion until the plants got to full size and then switched to a slow release organic 3-2-3.

Osmocote, Dolomitic Garden Lime, and Foliage Pro 9-3-6.

I use a mix of fir bark, perlite, turface, and potting soil in the following ratio:
5:1:.5:.5

Miracle Gro for the first few weeks followed by compost tea.

I like Green man's soil mix. I mix bonsai soil (from a bonsai dealer here, not sure of the ratio) With potting soil and I also use the foliage pro 9-3-6. Great results on both.

I have peppers in our sandy soil amended with compost and fertilized with fish emulsion. I also have them in pots and using the 5-1-1 mix from the container forum. I fertilize those with MG 12-4-8. I sometimes add a bit of epsom salts to both.

The peppers in the ground are still on their first flush of peppers. The pots are much further ahead and are producing their third flush of peppers. Both look very healthy. I suspect the main difference is the soil temperature is higher in the black pots. Both have excellent drainage.

i have been using Foliage Pro, 9-3-6 and was just given some
Genral Hydroponics "Flora Nova" 4-8-7 and since my plants are flowering i thought i would try it out at 1/2tsp/gal see what happens. the guy and the Hydro shop just gave it to me as i gave him a few Douglah.choc scorp seeds. he says it works great so we shall see.
