if you just watered ita few days ago then dont water there shoudnt be any run off when you water cause the roots dont have enough time to soak up all the water b 4 you water again
if that many hairs are orange and you want a head high then yes the tris should be cloudy but it sounds like its time to harvest and the top buds can get done b 4 the bottom buds........
yeah you can say that on one of my grows I didnt have any males at all but I still had a few seeds in my buds dont know where they came from but they where there so idk but yes you would have more thc and bigger buds
it all depends on how big you are going to grow your plants if they are going to be 5-6 feet tall then yeah but anything under 5 feet you dont need to go that big
