Bottle 3 not dispensing

Good morning!

I just did a water change on my Girl Scout Cookie (auto ILGM) on day 64 (26/40 flower) and I noticed my bottle 3 is not dispensing. I’ve checked for kinks and the hose appears to be free and clear so I’m not sure what to look for next. I never had a problem with any of the bottles dispensing on my last grow. and they all appear to be doing fine on this grow except for bottle 3. Any advice is appreciated!


First, I am blown away how well that plant has grown without bottle 3. You need to open a ticket with grobo support.
