Ok thanks for all the help guys, appreciate it.
I realsied that I have fertiliser in my soil, im using Bio Biz Soil....


Bio-Biz is an extremely high quality fermented organic compost for growers who donā??t want to mess about adding liquid fertilisers - itā??s all inside the compost, just add water for fantastic results. Add a bloom fertiliser when plants show signs of heavy flowering. Contains a careful blend of perlite, worm castings, peat, top soil and organic fertilizer.

So why am I getting yellow leaves on a 2 week old plant?... I understand that some leaves will die & drop off but I thought that was in a later stage of growth.

Im using Nirvana Top 44 seeds & 2 weeks since germination they are just 1 1/2 inch high?

Please tell me if this is normal, thanks.
