What would be the going on with this one? This is a White Rhino in a basic soil blend and 45 gallon felt bags. I feed with Flora Nova series. All through the year these white rhino my bubba kush and gdp's were all perfect. Then during flowering the White Rhinos started yellowing and the lower growth started dying off. I hope they last 2 more weeks to harvest. All the rest are fine. Green and budding well. What is causing this, so I don't make the same mistake next year.......
it could be a P deficiency, or you could have a pathogen growing in your soil. most likley a pathogen, if your other white rhinos are doing ok. a small ammount of H202 mixed with water will kill any fungi or bacteria in there.
