I use Big Bud in week 5. I've stopped using H&G Top Booster in week 5, since it has hormones that tell your plant it's gonna die in 4 weeks. I'm not using any PK 13/14 in week 5 or ever. Now I just run the Big Bud in week 5 same as week 4, then switch to MOAB/Kushie Kush (instead of MOAB/Hammerhead) and cut my base by 1/2 in week 6 and 7.
