nitrogen deficiency in gritty mix?
I recently created my first batch of gritty mix using repti bark fines, sorted and screened, gran-i-grit, and turface all sport. All the ingredients were well screened to eliminate dust. The repti bark is fir bark fine that are uncomposted.
I have a small pepper plant growing in it, and it is showing overall deficiencies, but primarily N.
Is this because the fir bark fines were not composted and are tying up the nitrogen? The deficiencies are showing in the oldest leaves and I am still getting new growth.
Sorry I can not post pics at the moment, but I will try to as soon as I get a new camera...
