What Happened To My Plant?(Pics)

Hello

Today I came hope to a VERY droopy plant it looked dead to me. I grow outdoor and the sun was gone so i put the plant under lights for about half hour. Nothing happened still looked dead. I then watered it because the soil seemed dry. An hour later it is back to normal but it has discoloration on the tips.

Sorry the picture is kinda bright but i hope the discoloration of the plant is visible.

My question is does anyone know what happened to this plant?Was there not enough water?

I would say she dried out, try to water her on a regular basis. The same shit hapend to me and she needed about 2 weks to get ok again.

ok thats what i thought, i think i will water her more often because i water her every other day. Do you know around how much water i should give her, shes about 3wks old now
