a couple leaves on my plant are wilting. before i continue, i am using a 75 watt CFL light, and there is a fan for air. the plant is like a foot tall,not quite in the vegetative cycle, so it's a baby plant.

so i think the culprit may be the fact that i may have over-watered the plant, some of the leaves are crunchy, like they bend and and break (only a few) and some leaves have spots on the edge of the leaves.

what can i do to prevent this, and make the plant 100% healthy? and what generic stores offer good supplies?
legalize.
