they are definitely shrinking so i've taken the fan off them now. not really sure what i should do they look like they are drying up and getting brittle and brown but the soil is wet. i just poked more holes in the soil for air. the top of the plants look ok but the rest look like its dying. would a transplant make them worse?

and the water ive been using is good enough to drink. tastes fine to me. i even let the water sit for a day before using it and still bad results
