Why would it make a difference in veg? I was planning on doing the light-proofing in preparation for flower.
I got rid of wpm with liquid copper fungicide, but the wpm did a lot of damage to the plants!
If you wish to stay with baking soda it's one level tablespoon per gallon which I'm sorry you learned the hard way lol but I'd recommend you spray every 3 days, not once a week as you mentioned
Wanted to add I had marginal results against fungus (septoria) with baking soda, never tried it against wpm? Good luck!
Also you need take leaf temps into account for proper VPD. I know the graph shows you a VPD but it's not as accurate as you think which can and usually does lead to issues like pm.
Here is the thread I made.
VPD (vapor pressure deficit)
Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...www.thcfarmer.com
That's awesome I haven't heard of one with an offset yet. Would you mind sharing the model?Nice thread - I'll grab the IR thermometer next time i take a peek in the tent. The app has a place to put a leaf temperature offset.
I don't like neem very much so I'll Reserve comment but I wouldn't mix it in like you're contemplating, if you want to use neem apply it once a week by itselfBumping it up to once every 3 days. Would hate for it to come back. I was thinking of adding some neem to the spray, to kill two birds with one stone - have you heard of anyone doing that?
Stress sometimes ya even see em flip upsidedown.Hi All,
Auntie here with another update.
Plants are looking happy after topping. Interesting to see how the leaves turn out after being cut, and to watch all of the new growth!
I got a spray bottle from home depot for my anti-mold spray. Definitely beats having to use a spray bottle and only $10. Highly recommended.
Before spray:
After spray:
I also set up a new drain hose. I think I got too big of a hose, I might have to look for some sort of fittings and adapters. It sure does make watering easier. I had to get a bit of a siphon going to get it started, but I just put the end submerged in a container outside of my grow, draining into the earth once the container overflows. I might have to get a little pump because I don't want to keep having to re-start the siphon. Will post more details next time I water. Letting them get a bit dry now.
Things have been looking pretty good in the tent lately. The jerky lines are from the exhaust fan coming on and the air changing over. Pretty happy with my averages! 76F, 60% RH and 1.3 VPD.
A question for you guys - some of my leaves look like this:
Is this something serious? What's going on here?
I can’t see your photos but i suspect you are wooried about the leaves clawing. If its mainly at night, its cooler temps but if it is with lights on and a little tip burn i think its overwatering and a little nitrogen burn. Letting them dry is good, real dry, then flush with water. JmoHi All,

Be careful when you are spraying the oil. Make sure it's right after the lights go out and there is plenty of time before the lights come on. That will burn the hell out of your plants if there is any left on the leaf surface when the lights come on. If you want to stick organic might look into using organic emulsifiers when using something like cooking oil. Here is a list but I can't vouch for any of it

Microsulfur/burning sulf/h202 will work better then that. The baking soda is just for changing the leaf PH. There is also stuff like stylet oil (JMS) but I havent used it as a full treatment from start to finish to tell you if it really works. Some OD people I know use it religiously and swear by it. I never really cracked into the bottle heavy.0 Have it more for pests now and preventive. Same precautions go with that tho. I always use something like coco wet with it.
So far I haven't seen any burn from my last spray, so I think it was dilute enough to not cause any burn.
Im going to be switching to flower pretty soon, and am getting kind of worried about what to do for pest & fungal management when the buds start growing. I don't want to infuse them with weird smells / tastes / chemicals. What would you suggest for flower?
Your only real option there is H202. Sulfur will def effect the taste and smell. Problem with h202 is it's more of control. It's not a cure. Stuff like baking soda sprays will turn the pistils brown in flower unless you find the right happy medium. Even then I don't like it. Why I never liked stuff like Green Cleaner. Def affected the end product.
I guess I'm stocking up on some h2o2 soon!
