Yesterday I dropped by the nursery to purchase some containers and showed the pictures to the lady.
She was sure that it's a case of over fertilization, she said the leaves are mirroring the root damage due to strong fertilizer use.
So it looks like my mistake was to transplant the seedlings into miracle grow potting mix (which has fert) and to hit them with a full strength of fertilizer with every watering.
According to her, the blue stuff should be at most once a month not once a week.
I think most of my plants will recover/survive, except for my WhiskeyJacks, it's frustrating because because I seeded them first, gave them the largest container, the best spotlight and the most fertilizer love. Now I have to restart this variety, at least it's not too late....
Funny thing is I planted 1 SivlerFir Tree to see how the plant looks like and lo and behold it's about to flower! Fertilizer abuse barely scratched its lower leaves
too bad it's not known to be a tasty variety
