IPM stuff/questions

Recently acquired a vested interest in a rec grow, I am also doing all the gardening for a salary...

I inherited some (very sad) vegetative plants that should have been flipped two weeks (at least) prior to my arrival. Its a brand new building, new build, and this will be the first crop on the license. The plant inventory I inherited is from clone. I despise clones for all the reasons they are and should be despised lol...

Long story short: growing this many (400+) plants from clone has been an impetus for me to devise a more clear IPM program than I have ever needed to before. 20 years of organic dirt farming, a little hydro, and I have never had PM (never used a single clone, either). I have experienced PM on close associates of mine's grows and in a consultation faculty (and I usually counseled they send it to the extractors and start fresh). I have 200 Rude Boi on day 20 of flower with PM. Mind you, not all 200 exhibit PM (maybe 20 total did), but since the other two strains in the room have shown no PM, I can safely assume its in the Rude Boi. I have taken all the corrective actions I can. RH peaks in the low 50's occasionally, but stays mostly 39-45%, and was always the case. But temp has been adjusted from 75 to 81. Air exchange is sufficient. Potassium carbonate+castile soap spray. Regalia in reservoir (rockwool substrate). I interface heavily with the plants, so I caught PM immediately and I am confident I can manage it. Plus, there is a financial impulsion to do so. So...I have been cramming on fungicide technology this past couple weeks and I have a few questions that I can't easily google re: mostly fungicidals.

1. does citric acid act systemically or translaminarly or neither? usage specs?

2. what are the usage specifications for lactobaccilus acidophilus in cannabis cultivation? foliar? reservoir?

3. anyone with actual firsthand (not anecdotal) experience using UV light to eradicate pathogens in a grow?

4. (not fungicidal) is KOH too dangerous to handle for pH adjustments? (I keep seeing that scene from Fight Club in my head). I am watering high ppms and looking to find a better pH adjust than the over the counter solutions. Tried potassium carbonate, very effective, not as cheap as I want it to be.

thanks in advance for any input. cheers!

Hmmmmmm.! Ok I gotta tell you I have been in a very similar situation and then the boss died in a car accident

the growing was ok...400 sativas in organics with most outdoor in flower

1. does citric acid act systemically or translaminarly or neither? usage specs?

Citrate can be transported out of the mitochondria and into the cytoplasm, then broken down into acetyl-CoA for fatty acid synthesis and into oxaloacetate Yes ...see wiki

2. what are the usage specifications for lactobaccilus acidophilus in cannabis cultivation? foliar? reservoir? Not used but I know of it

3... anyone with actual firsthand (not anecdotal) experience using UV light to eradicate pathogens in a grow?

Pathogens in a grow is a big No No fire your compost guys UV does poop, but is good at finishing trics after bad weather

4. (not fungicidal) is KOH too dangerous to handle for pH adjustments? (I keep seeing that scene from Fight Club in my head). I am watering high ppms and looking to find a better pH adjust than the over the counter solutions. Tried potassium carbonate, very effective, not as cheap as I want it to be.

KOH(гидроксид калия) is a damm hassle, as it already got water in it.. its very difficult to use and even goes mushy in the air, I've not used it for like 30 years since we got a good well
and filters ..I suspect you have issues with your water ..? also its expensive even drilling your own well has to be cheaper over time

I still grow volume plants but customers demand total organics for which I charge a serious Premium, my tools are Honey for first aid, Neem Oil to suppress bugs and mold, Aloe Vera as a surfactant..the less the better

good luck and post pics

Don't grow organic, but I used organic while in the golf maintenance biz at least the last 15 yrs of my career.
If I were to grow cannabis organically I would use the same rules I used while growing turf without chem's.
Proven tested organic vegan compost, high grade vermicompost and EM1, I used it as an organic in my topdressings, and as a tea. For the greens we would make a 250 to 300 gallon tank of the compost and the vermicompost then add extended EM1. This would be added at a rate of around 15 gallon pure tea to 500 gallon of well water and hand sprayed per green.
This would produce the best root system and healthy turf, very disease resistant and thick putting surface.
This was only part of my program but a very important part.

You guys are confusing uva/uvb/and Uvc.

Uva/b is good for plants

Uvc is deadly to plants, people, spores, and anything living.

I build custom uvc boxed for growers. Very strict precautions are needed when using a uvc system.
