problems with seedlings

i learned the hard way and fed these ice seedlings Thrive Alive thinking it would help them build roots faster.

they are about 2 1/2 weeks old and have been the same size since i nuted them about 2 weeks ago.

i flushed them with RO water several times about 10 days ago and they really haven't showed any new growth..

i feel like i'm wasting my time and electricity trying to make them survive and i have been thinking of just throwing them in the trash and starting over.

why haven't they recovered? they been getting RO water for over 10 days. they are still sort of healthy looking but they aren't growing!

how much longer will it take before they recover (if they ever do) or should i scrap them?

i'd hate to trash them because they are all female seeds, but im growing impatient each day i see them the same size. i'm giving them 18/6 lighting.

any advice?

im a sucker i would give them more time

u may have burned the roots, but ide deffo be more patient and give them more time, never feed seedling with anything but ph'd water for the first 3wks, than u can start using neuts at 1/4 strengh of reccomended dose!!!!!!!!!

ide also smack em under 24hrs light for first 2weeks then down to 18/6 for 2 wks then switch em over to 12/12.

only my opinion. good luck
