Drooping Stalks

Hey, I have a batch of about 20 Grape Crush clones that, after being fine a few days ago, have been exhibiting a few issues. One, they have had a few small, faint brown spots appear on the leaves, and two, the stalks are becoming very droopy. I've got a variety of other clones in our clone room, and this is the only strain that seems to be having an issue. I've attached pictures.. Anyone have any idea what is happening?

2nd case of stem rot this week.

You should transplant all of those cuts ASAP into proper soil before they all die... Whoever made those cuts is not good. It looks like there is mostly mulch in the potting mix lol ... Is there even any roots coming out the bottom?

I think they will be ok, keep temps 75-80. Some clones can droop a little and be fine, if the leaves sag down they will need re doing. Causes could be a poor quality mum and wrong stem cut.

looks like they were really liking that humidity dome
