HELP! Seedling looking like Nitrogen def. or burn ?

Growing in FFOF . Normally use FFHF. She is 2 weeks old on Monday. White rhino strain. Suggestions please ! I assume I need to transplant into something with no nutes or wait it out ? She is still growing haven’t seen any stunted growth? Took out root ball roots look healthy as well ‍? First pic has a flash in the dark second is just sunlight

FFOF is pretty hot. Stay away from ferts, water thoroughly when dry and light.

It’s already hungry why would you transplant it to something without nutrients?

Have you been ph’ing your water?
