I use a small artist paint brush to pollinate mine. If I wish to use several types of pollen I spray with tap water the buds I DO NOT wish to pollinate. Then I can pollinate the others. Bags are good too but you can't always fit a bag properly.
wOW, GREAT JOURNAL....I HOPE YOU GET THAT LEAF DROOPPMG UNDER CONTROL, GREAT INFO HERE!
It's hard to say about the pollen timing. Some of mine were rapid and some took a while. Each strain is different. When I say spray I mean spray water from a small hand held manual sprayer. I get it close to the bud I want water on. For example I pollinated a short term amnesia with Ducksfoot pollen on the lower buds using a brush. I waited a few days. I then sprayed with tap water the buds I just pollinated with Ducksfoot then with a small maybe 1/16 inch or less artist brush I brushed short term amnesia pollen on some of the upper buds. I believe you have to use tap water. There is a thread somewhere that says if you use rain water it will not deactivate the pollen. Maybe it's a ph thing when using rainwater.
Have a look at the first pics in my grow thread "test grow Purple Concorde and speedy gonzales" mine looked about the same as your Lady and the was because my soil got to compact, thank you ICC for pointing me in the right direction. Think your having the same problem, the roots arent getting enough oxygen. Repot them in to your air pots and get the soil mix right and she will be fine. The sooner you doit the better, mine took about 4 days to recover after i repotted them.
Good luck.
