Acquired neglected plants, what do??

hey guys so i myself am a beginner grower and i took in these 3 plants from a friend of a friend and its supposedly "grandaddy purp" so i was all over the offer but when i got the plants they were in horable condition here are some pics. i do have the room in my veg area to hold these but the question is:

A. do i try to salvage these plants and see if i can nurture them to a better state of being.

B. try to take as many clones from it as possible and throw away the plants and hope for the best.

like i said im a new grower as well and there are some pics of the damage i dont even know where to start. i currently put them under 4 4't12 florescent and am watering daily. is this worth my time?

Fluuuuuush with as much water as you can put through those pots. They are seriously nute burned and i would give them straight water for about 2 weeks after you flush them. After that, make sure you are testing the pH and give them small amounts of natural fertilizers

Agreed... make sure there is a few drainage holes and pour like 30 gallons of water through each pot to flush out the nutes.
That plant is nute burnt to a crisp, hopefully you can salvage her.... the nute burnt shit wont ever get better but the new foilage should.... flush it HARD and just feed plain water.... should get better.

there's easily enough green spots to recover from that burn . . . .
