depending on how long you already had plant under that light i would keep them 2 feet away slowly lowering them every 4 - 5 days don;t worry about stretch because when you re plant them just lower them further into next pot size lower light 7 inches in intervals till you are about 12- 14 " away from, plant depending on heat place your hand above plant if your hand burns then its to close

What DeFever said, the hand method is the best I know of. Light as close as possible, if your hand can take it, your plant can take it.

Thanks guys! Just done the hand test and it's all good! Only concern is the temp which is at 83.5 F so just gotta get that down a touch!
