dyign plant!

ive just grown weed in my backyard and moved them into seperate pots and put them in an aluminium foil covered space with a fluoro light above it.
the plants are dying now but not the one that i left in the original pot.

if anyone has answers it would help alot.

I dont think alluminum foil is a good idea, were you carefull not to hurt the roots when you transplanted them?

you might have cut the hell out of the roots

yeah when i transfered them i was careful but its my first time so i may have damaged the roots. is there anyway of helping it re-root? or will it just fix itself over time?
