Indoor Mutant Zamaldelica

All 3 Zamaldelica are reunited for bloom. Plant 1 is the tall, slender, racy wild Sativa I've been dreaming of. Standing at nearly 33 inches, she is just starting to show pre-flowers. This is week 2 after flip for herStill a few days before the real stretch begins. She will be a queen. Plant 2 and 3 were transplanted last Sunday after harvesting the All Gaz Og. Soil was amended with Kelp meal, Gypsum and Basalt rock dust. I can already tell it was not enough, seeing some K def before flower starts to grow. Not easy to manage and understand the needs of lower feeding strains. Always looking for minor signs of deficiency without knowing if they are nute burns. With heavy feeding strains, I would just pack the soil and wait. This is especially harder with recycled soil. I can check soil ppm, but it does not tell what is missing. Plant 3 showing some pre-flowers is pretty early, 6 days after flip.
