i cut some clones . put a root gel on them . put them in rockwool , they stood for about a day or so and have fallen over , there not cut to long and have trimmed the leaves does this happen normally?...
Ok sorry for the stupid question but the only time mine have droop is if I removed the dome to early just use a small nail or somthing similar to stand it up (make sure whatever you use is clean) and mist the inside of the dome not the clone and it should perk back in a day or two
good luck
