Hawaii outdoor grow (any advice?)

Hi everybody!

I was wondering if anyone could look at these pictures and give me their opinions on what is going on. The first two pictures are of these white bloches that are on a lot of leaves on different plants. They have tiny black spots on the back of the infected ones, which leads me to believe that it is not sunburn (which is what I previously thought). If anyone can give me any advice on this problem, I would greatly appreciate it.

The third pic is of a lady in veg not yet flowering soaking up the sun. I know that it is at this stage that I should top it so I can have a shorter bushier plant. I am fairly inexperienced, so I don't really know what or where to cut. Any help with this would also be greatly appreciated.

The fourth pic is one where alot of the white hairs are being replaced by pods, so I just flushed it and gonna let it go for about another week. Does this sound about right? And if not, what time frame should I be looking at?

The final pic is just one to give a sense of the amout of sun that they recieve, which appears to be doing them well except for the white bloches.

Once again, I am just an inexperienced grower that really really wants to learn how to grow really really good medicinal maryjane for personal use.

Thanks again everyone,
Rider

I could be wrong, but your leaf problem appears to be a zinc deficiency, charcterized by the white blotches and green veins, or it could be potassium. You are so close to harvest, though, I wouldn't fuss with it. Next grow, use a different potting soil or topsoil and an all-purpose fetilizer. Nice buds, man.
