4th week of flowering. Trychome production is better, but I don’t really like the buds density. I've grown like 5 Northern lights from different seedbanks and all of them have not the best structure of the buds.
@spab149, To be honest, I don’t think you'll like this strain. Probably, It's most known strain worldwide and that’s why everyone’s still growing it. I would grow Purple queen for my first grow, easiest to grow and most potent! one of the best strains from ROYAL QUEEN SEEDS.
