Time kills Terms?

So I'm on my 6 round in a perpetual grow of serious seeds Bubblegum. I have been letting it go 10weeks total in flower. 8 with nutes two flushing. I have noticed that weeks 5-7 I have the strongest bubble gum candy amazing smell. But come harvest time it turns to a catpiss smell(not bad kinda dank but not the bubblegum I want) could it be possible I'm going to long. I usually go by the 50% amber rule but this s high sativa strain. I have a 60x loupe but have trouble looking into it clearly and don't wanat to cut off a bud to look. Thanks in advance for the help. -cheers

Yeah you could be running a bit too long. When you harvest is more of a preference, I always considered the "xx% amber/white" more of a starting point.

Maybe try clipping a couple buds (maybe dedicate a small plant to the experiment if you have the ability) when most of your buds are milky white and some are starting to turn amber. Then clip another bit every few days (make sure you mark the bags/jars when you do this) until you get to the usual spot you harvest)

Hopefully this helps you out! Good luck pimpin'! Stay red eyed, smilie & irie!

My bubblegum was always done around 8 weeks, maybe a few days longer.
