Grow less plant. The leaves drip water with hydro. You gotta get more circulation. Grow one plant less.

No space in the tent. Max out is 6"
Less plants and more defoliation techniques.????

Thinking out loud again.

While I'm at it.....I don't advise bleach for cleaning grow area and equipment between grows with bleach for mold issues. Proven to increase spore release. And at dilution rates used it not 100% effective at killing those spores. Add to this the fact that chlorine evaporates rapidly. Leaving water and fairly inert salts for the spores to attach to after you spread by wiping. I suggest a fungicide followed by ISO with fans running to get ISO into and on spores there. I try for short of perfection indoors.

Thank you for your help ! I will work within these guidelines.

Why do I still feel like I don't know what to do ? I can't find anything on Amazon or in my local grow stores. Am I defeated ? It feels like I should quit while I'm behind. :(

Just started too big. We all over do it still.

Just be sure you have cleaned everything after grow. Do it better from what you have learned. Ask your mother how many times you fell down learning to walk. Such is life.

You can try a 10:1 water:milk dilution. Usually by the time it's on your buds, it isn't worth smoking anymore. You will want to wash your buds with H2O2 dilution before smoking. Otherwise just make edibles from it.

All you can do is fight it once you have it and try to keep it managed. I'd get some potassium bicarbonate and hit them with that to start. You might need to use sulfur too. I never use any of the chemical fungicides though, up to you whether you want to go that route. In the future you will need to focus on prevention, it's much easier to prevent than to treat. Treat your plants with biofungicides early and regularly, give them aspirin water a couple of times, spray with neem/silica, etc. Try Regalia if you have the funds, it's a great preventive.
how much aspirin per gallon?
If you do try aspirin be very careful not to overdo it. I read somewhere (Ed Rosenthal's website I think) that a low dose is good for your plants, but that a higher dose can act like CS or STS and cause your plant to hermie.
ANYONE GOT ANYTHING I CAN BUY FROM AMAZON FOR THIS ?
Potassium bicarbonate. I got mine on amazon. It might be available at a brewer's supply shop too. It's used in winemaking to raise the ph of wine when it's too acidic.

I wouldn't use potassium bicarbonate in flowering, unless you wanna smoke the residue later. A water/milk dilution will enzymatically break down by the time you are ready to smoke the buds.

I used it in flower as a preventive spray for bud rot. Only lost a tiny side bud in the 2019 season. You can rinse any residue off, but you don't need to as it has no odour, no flavour, and is safe to ingest. It's KHCO3, and its melting point is north of 550f, so you shouldn't be inhaling any when you smoke it. It's also allowed for organic gardening.

I've used it many times. I'm quite aware of how it works, what it does, and how it affects the flowers. That's why I would never use it on buds, but hey if you're happy with it, you do you.
