OK - I’m about 6 weeks into flower on an outdoor grow. I’ve got 4 varieties (6 plants) over 2 grow sites, both of which are affected similarly. After hours of research, I am fairly certain I have a severe case of Septoria cannabis fungus. This is a damn shame. I’ve moved past the four-lined plant bug attack earlier in the season. Although I lost a few substantial limbs during EXTREME winds we’ve had recently, most were saved by bamboo staking . 10 days or so ago, my ladies were in near perfect health, standing 9’ tall, 8’ wide, and flowering nicely. around 10 days ago, we began to get pounded with rain. every day… rain…rain…wind… rain…wind… In my reading, I discovered that this is the perfect condition for Septoria cannabis fungus to arrive and spread. It spread like wild fire. I could almost notice deterioration by the hour and not day. I realize that the damage is to a point where I’ll incur substantial loss of quality and yield. I guess what I’m looking to do (without driving myself nuts…lol) is to salvage what can be salvaged, and move forward best I can. If anyone is familiar with this issue, or can concur my suspicions of Septoria cannabis fungus are correct, please give me your insights. Assuming that is the issue, I see only a few options
do nothing to combat the fungus. hope that the flower production can “out run” the destruction of the plant / flowers. possibly harvest early would be prudent?
neem oil or some other fungicide? everything I read says not to do this in flower stage. will ruin flavor and smokability.
let them flower until trichomes and pistils indicate it’s time to harvest? I will say, that the more affected plants have more pistils turning red faster that I think they should, whereas the more heathy ones are mostly white as they should be at this stage.
In any case, do I have a chance at a decent harvest, or should I write this off as one big and painful learning experience, and move on to preventative measures next year.
ANY HELP IS MUCH APPRECIATED!!! T.I.A.
