On a related topic but not strictly a reply to your post i'm afraid..!

I'm trying Jalapenos for the first time this year as well. There are
probably numerous things i've done wrong... one of which is being too late
in sowing - now have 12 1.5-2ft high plants with only a few tiny peppers
emerging...

Anyway my question is - The ones i've planted into peat-free (i.e. quite
woody) growbags have quite yellowed leaves. I initially assumed this was
from overwatering as I believe my friend drowned them daily when I was on
holiday, so I didn't water them for a few days and although they're looking
a bit healthier they're not exactly thriving (and still yellowed). I've fed
them with general purpose feed about once every ten days over the last few
weeks, but overall a bit disappointing.

One thing that's maybe quite telling is one plant I didn't transplant, which
is still in a pot now much too small for it seems to be doing at least as
well as the ones I transplanted into the bags a month ago, and much greener.

Any suggestions? is it the peat free bags i'm using? They seem more like
bark mulch than useful growing medium.

Any suggestions welcom, Cheers!
