I've gotten a batch of weed a long time ago that looked awesome and didn't get me high either. I was told by someone that the weed was vaporized and the THC was removed...
Don't add fresh to stagnant water... change out the water with 100% fresh water every few days. Keep on eye on the Ph levels in your water too....I noticed that the brown slim tends to build up more on the roots as the water loses it's acidity.
Best of luck!
Are you implying that if a plant is not "trimmed properly" that that would cause mold?! I've never heard of this before and would like to know if this is true.
Try rising your roots under the faucet and gently using your fingers to wash the brown away. Also, frequently chenge your water and keep it fresh! Hope this helps...
This thread made me feel itchy. I hate f-ing mites... luckily I didn't have the super spider mites you did. Thanks for keeping us updated on what worked for you!
