Yes, a beast PK would be nice. I also have Bubba Kush and I find them very similar and that's one I would also like to veg for like 10 weeks lol. For some reason I don't get any stretch with my PK, but the room was cool so as you say, now that summer is here with the heat I might get more...
Yes I usually prune the bottom fourth of the plant also, to promote better air circulation and increase cola size. I wish I could post a pic of the crop I did of PK but unfortunately didn't take any. It would better illustrate my reasoning behind leaf removal. I will take pictures this next...
Sorry, I should have not used the word 'many', my bad. I never remove many, just a few during flower every few days. I agree 100 percent some people strip a plant and this is not beneficial. But I do believe some removal to be good. By looking at your picture I can see why you wouldn't want...
Removing fan leaves on a plant that is not very leafy is not a good idea, you are right. But in the case of Purple Kush it seems to help out quite a bit. I don't go overboard removing leaves and you should never do that no matter how leafy she is, but a few every few days won't hurt.
The way...
If your extraction fan is extracting more air than can be taken in through your passive intake (which is a good idea to use) then you should be fine. When you get set up show some pictures, should be interesting.

There are many different answers for this, but since I like larger plants I would grow four and veg for six weeks (depending on strain and stretch) and bud under 1000 watt hps. You shoul get a pound fairly easy. If you like smaller plants do eight with a three week veg. A good idea if you...
In those pictures you posted, are those pine needles? If so that is your problem. Pine needles are highly acidic meaning you ph is causing nutrient lock out.

What temperature is your room, min and max? That soil you are using I am not familiar with. Does it contain nutrients, and if so which ones and how much? More info is always good.

30 degree's is too hot and it looks like your plants have slight nute burn although as tokin24/7 said it could be due to heat stress. Other than that they look ok. The reason the buds look small is because they are a little more sativaish (new word lol.) than the others. I doubt in 5 weeks...
They should be fine. Next time sprout them under a light. You won't have yellow babies and they will not stretch as much. What kind of light and wattage do you plan on putting them under?

It could be that the bottom leaves are too close to the soil keeping them wet and causing them to die. The reason I say this is because the rest of the plant looks healthy. I would snip off those bottom leaves and see if other leaves change. But I wouldn't worry until another leaf dies not as...
