It's not all that common for the leaves to be reaaaallly droopy. But sometimes they are - and then there is the usual disclaimer that, of course, everything is strain dependent.

Make sure you mist the inside of the dome and not the cuttings! Keep a close eye on the cuttings and immediately cut off any leaf parts that start to rot. If stems are bending, you can prop them up with a bamboo skewer or something similar - I use chopsticks.

To actually answer your original questions, your lights sound fine and your temps should be in the high 70's -mid 80's, so you might want to use the heat pad.

Good luck with your clones! :thumbsup:
