Lots of Pic Mo Problems

1. Is this male of female? This is my biggest and strongest. But in two short days the inner leaves started browning


2. This is my weakest it has gone form bad to worse! Super brown on bottom with some nice green on top. plus wtf is that??
Webs?


3. This plant is ok Green on one side brown on the other. The brown side was facing a larger bush of wild plants saw grasshoppers and other critters in the thrush.

Look at my bud i dont even know if its ready?? it looks soo good though help me save these babies! I know for sure that i have the following cutworms, grasshopers, moths, and i think spidermites can i use anything or is it too late? Should i try to trim them in a way that makes them bud again really fast?
That top one is healthier but its right next to my sickest plant (same pot) so i dont know what to do

the sick one look like its very ill its got the blackdeath. only messing but id see if there any insects and get rid if you can and i think the plant pic 1 is female.plus are your plants really wet at the bottom near the soil if so dont water as much.where you from england?

its rainy season here, and i grow outside...
what is black death?? that one needs to get thrown out then?
if they are all next to each other wouldnt they all be sick? i hope she is female
what about the other ones that are only browning a bit?
