If it was me yes,Also i would fill the pots up with more soil and cover most of the stem up so it wont be so lanky .Also what kind of soil are you useing (good soil will make a diffrence like night and day.)

Yes get more light in there ,Also the first 2 -3 inchs of each tube does not put off any useable light
