Okay so check this out, my harvest before last I had a similar issue with lack of that typical dank smell from my buds. My logs show that I was running a relatively high pH range @ 5.9-6.1. Then in my last grow I was running at a similar range and noticed the same thing... lack of smell in the middle of flower. I noticed this time though, that there was a strong smell durning veg, when I was battling pH swings. Because the pH would rise so much day to day, I was lowering the pH to 5.1 and letting it rise to around 5.9 over a 24 hour period. Then by mid flower the pH was stable at around 6.0... so I left it... but the oder was gone. So on a whim I started lowering my pH down to 5.2-5.5 and low and behold the smell came back!
Now I can't say with any certainty that this was the one and only determining factor, I know lots of people run high-range pH grows producing heavenly aromatic buds. This was just my experience and wanted to share. |
