Also am I doing the right thing by cutting these spots off? I have been trimming half the leaf that has biggest amount of spots.
Another issue I would like to know about growing in an indoor tent. Dehumidifier makes the room dryer but hears it up drastically. Then the ac unit has to work really hard to offset the heat. I have the tent intake bringing air from outside and sometimes take the flexi vent out of tent so it can pull in room air when it’s over 80F outside so I’m not pulling that 95f air into tent. I suppose I could do this so I’m not pulling that humidity from outside too. I my exhaust goes outside as well. So back to keeping the room in the right zone, how do you keep it dry and cool?
Well I guess I would start by saying you need to know where you should be on the VPD chart. Obviously you are in late flower but only you can check your leaf temps and configure YOUR chart on those parameters. To answer your direct question…if you need to drop humidity and temperature, a AC unit would effectively do that for you!
Yes you can cut off infected leaf parts, but that will have minimal impact on stopping the infection. Briefly, fungi spread by releasing their spores when conditions are conducive to reproduction. Since you are seeing relatively new infections showing up, you have to assume the spores exist on your plants already and will continue to be shed with each new infection point…
My best advice at this point in flower may be the use of Hydrogen Peroxide sprays every 3-4 days to eliminate new infections and eliminate innoculum…Hydrogen Peroxide (H2O2) leaves absolutely nothing behind on your bud and breaks down into oxygen and water…FWIW
Ok then I’m on the h2o2 spray right away. I’ll research best time of day for that before as well cuz this is my first ever grow. I’ll cut infected areas best I can without shocking her. Will the buds be smokable still with something like this or would it make you sick? Lots of research for me tonite. Lol
The fungus infection you have is a little hard to diagnose at this point but it is more foliage related than a danger to your bud directly. So the good news is it will not directly effect your bud IMHO. Indirectly a foliage desease will kill your leaves at this very important stage where they need to be transfering their stored nutrient to the developing bud…so the good news is if you can contain it quickly you will minimize damage and be OK. Looks to me like it might be Septoria but more likely a early Alternaria infection.
Hydrogen peroxide (H2O2) is a better disinfectant than bleach without the problems associated with chlorine levels in your plants. It kills bacteria, fungi, and even viruses on contact. It’s only shortfall is it is neutralized fairly rapidly…hence my advice to hit it every 3 days or so…Best of Luck!
don’t use bleach unless you want Hermie seeds and save the peroxide for cleaning, em1 will rid fungal issues faster.and safer imo. not that I think he has fungal issues.but it never hurts to use em1 when in doubt, best to stop spraying em1 a couple weeks before crop.thilo I have no clue why, I sprayed buds already dead with no taste or harshness issues
Ok so when lights are on my tent reaches 78F and hangs at about 55% humidity. From that chart it looks like I need to drop humidity to 45%… is that correct? Would you recommend I spray the affected leaves with h2o2 3% mix 50/50 with water? The flowers seem to still be growing rapidly. Sorry if I’m asking too many questions, I’m just worried I’ll screw it up after getting this far.
At night the tent hovers around 70F and the humidity climbs way up to 65% and keeps online fan running strong all night. I’m afraid to put humidifier on in same room due to the a/c unit fighting against it constantly.
Finally, I think I may have invited the fungi in thru my air intake which goes thru a basement window which is only 1 foot off the ground outside behind a shaded bush with lots of dead leaves and debris on the ground. Do you think the intake needs to be from outside or would it be better to draw air from the actual room it’s in in the basement? I removed this intake from the window yesterday and found the fan runs a lot less which is a lot less airflow. I do have 2 small fans blowing air around inside above and below canopy with an exhale bag banging above it.
