You'll want to keep your temps under 85'F, that's probably one big cause of the stress. If you're using C02, you can allow the temperatures to get a little higher... but without it, plants respond better to slightly lower temperatures.

And if you've got plants that are covered in pollen sacs, then it sounds like you've got a male... not a hermie. If you took clones from a male plant grown from seed (which is not uncommon), then all of your clones will be male. Sorry to be the bearer of bad news, but at least it sounds like you're taking good care of the plants. Get yourself a female and try again! :jointsmile:
