I have 3 Northern Lighting Automatic with 14 days of life. They are on the init state building the 3 and 4 true leaves on a 1L pot with:
40% perlite
40% peat
20% earthworm humus
I have the following fertilizers with me:
- BioBizz Fish-Mix
- BioBizz Bio-Heaven
- BioBizz Root Juice
- BioBizz Bio-Grown
- BioBizz Bio-Bloom
My question is, when to start to fertilize? Should I wait until the decotyledons or the first leaves start getting yellow (nutrient deficience) and then start with fertilizers or should I start with them now and observe the reactions of the plant?
