The more you spend the more you get, will smell be a problem? You're not gona get what you want if you dont spend some money. Although I have seen weed grown cheap, but if your grow again your aswel spend the money and get the gear.
Besta luck!
I have the same problem with the same age plants, I had a fan blowing directly on two of them, these are the only ones affected. Im gona flush and see what happens! any info appreciated!
