moved sprout from soil to aero, looks like burning?

Plant was pretty young for the move, (just under 3 weeks) but i didnt want to repot in soil and then move later, and the roots were showing in the clear cup i had it in

Looked good the first 24 hours, then started getting some burn looking stuff on the first 4 leaves... the new growth looks great, its just those original 4 leaves that look bad... Hopefully this is just stress from being taken out of soil and moved to something else? I also have 3 other seedlings in the aero setup (started in rockwool) and they look fine. So I would think that rules out the lights and the nutes? (light is 400W MH, over 2-2.5 feet away) Nutes are 1/2 of what was recommended for seedlings. I'll have to get the exact brands.. There is a base and a veg. I do have a tds meter but i havent measured it yet.

Sorry the pics arent very clear, but hopefully clear enough... if not let me know and i'll try to get some better ones.

thanks!

just tested ppm, it was 352... my water from the tap is 170 before doing anything, so i guess that means the nutes + small amnt of superthrive i added is 180ppm.. possible its deficiency ? hopefully just shock

could be something as simple as nutes got on lower leaves n burned em as newer growth is still ok .

should i remove the burnt flowers, or wait to see if they improve? if i do remove them, do i remove the flower, or the stem the flower is connected to ?

plant is growing ilke crazy, but those original 4 leaves still look bad.. not getting worse, but dont look better either
