That's a nitrogen def, like some have said on this thread. Its normal at this stage, don't add any more grow (nitrogen) that will cause fluffy budding. That's why you are supposed to cut the grow nutes out late into flower..plants look great!!!!
yeah thats about what it is in my neck of the woods too, sometimes worse that 1.5 eightballs. i remembered when it all started wiv a bad drought a little while back but where every1 was willing to pay drought prices its just stayed that way because why would they ask for less money when people are willing to pay more.
