I think it is kind of ironic that small germinating plants start yellowing due to nitrogen deficiency but I think it has to do with their root systems still developing and getting nitrogen from the soil is tough for them so when they're real real young, I'd say once they've developed around 10 leaves they will often start to yellow. They are growing so fast and their root systems are not fully developed to take in all they need. Foliar feeding as well as using liquid plant food nutrients. I recommend a light nutrient solution at about half strength and some SensiZym to promote root growth as well as a product I swear by which is Bushdoktor Kangaroots. The Bush Doktor has all kinds of good stuff in it like MYCORRHIZAE and beneficial Bacteria. It is derived from Earthworm Castings, Manganese sulfatem Zinc Sulfate, Hydrolyate and Kelp. Without going into a lengthy explanation it is basically microorganisms that do a lot of the legwork for processing the foods plant. Adding anything to help that process really helps. So, basically what that means is your plants will love it and make it easier for the roots to process and break down food. More root, more fruit. SLM and BLACKBERRY are looking healthy @ Blazin. Give that yellowing Afghan Kush a LIGHT dose of vegetative nutrient solution and the yellowing should stop almost overnight. Best of luck on your grow. I am growing many of the same strains you are growing.
