Leaf Problems: + rep for any help

Okay so I might have a problem, not sure yet. I am a few weeks into budding on one of my outdoor plants. The temperatures here get in the 80s in the day and high 40s and 50s at nights. My grow medium is a mixture of compost and horse maneur. I feed my plant MG Bloom booster in light doses every other watering.

Thats the conditions and here is my problem.

1. My most bottom leaves are dieing off. I thought maybe this was from the flowering because I have had them do that halfway through flowering before, but it looks like my next row might die (not sure). So, I figured it couldn't hurt to post pics and see what it might be.

2. Another thing bugging me, is these spots on a couple of my leaves. Pics are included.

3. Last, On a few leaves, and on leaves around buds (not on buds) there is a whitish like mildewish spot. It wipes right off, and doesn't seem to be hurting anything but yet again, better safe than sorry.

All pics of the 3 problems are shown below. Thanks to anyone helps and + rep!

^Yep, agreed, you have powdery mildew. Best to get it under control, fast, as it can spread rather quickly, and do lots of damage. I never had to deal with it, so can't suggest anything that'll work effectively in eliminating it. I've read that H2O2 works, as well as milk, mixed with water and sprayed in the foliage.(one or the other, not both.lol)

Any suggestions, or personal results/preferences?

Damn, glad I posted this. I've never had to deal with this mildew before. So just mix milk with water and spray the infected foliage? Seems sketchy but this is a good plant that I would like to save.

Thanks so much for the help, it gives me a start on things. Any suggestions on those leaves or just natural stuff?

Anyone else have any ideas to my problems? Please could really use the help

My buddy uses sulfur to treat mildew.. Worked real well.. Also, I know you cannot control this but going from 80 at day and 40 to 50 at night is going to shock your plant... That may be the wilted dead leaf you have pictured.. Cannabis is unhappy temperatures lower than 55. If it goes lower than 40 you might wake up to a dead plant..
Also, I wouldn't spray milk on your plant, go to the grow store and get something designed to treat mildew.

Ive had the Milk work really well for me. Good Luck!

Yea, I have grown in these hills for years, and the temperatures don't help the plants don't get me wrong, but they haven't ever killed them. I usually leave my plants out to early October and it gets down in the high 30s and low 40s at night. It may be the strain, because I've grown the same outdoor strain I started from bagseed years ago, and I just continue using seeds/clones from it. But thanks for the input and I got the mildew problem under control, used some fungicide I had and it seemed to cure the infected areas. I'll just have to make sure it don't come back. Thanks to all who helped.
