I used Coast of Maine for the first time in pots and also had issues. This after years of outdoors in the garden, with native soil, mostly augmented with cow manure added to the garden soil in the fall and turned again in the spring.The amount of money I spent on this grow..my goodness...it's embarassing to have any issues after throwing so much money at it.
It has been such a tough grow despite using premium products. I used buildasoil and coast of maine soil, rootwise products, silica, aloe vera, compost tea, amino from cod, peach extract..probably forgot some things. Meanwhile last year, I used only native garden soil and the grow was 99% uneventful. The native soil in my garden is premium from decades of composting and organic farming though so maybe it's my fault for overcomplicating it this year..but I digress. ALOT of lessons learned.
Truly appreciate the info you shared. Thank you again!
Glad to see that your grow is going to come cross the finish line, nice looking buds I might add. this year has been a non stop onslaught of really bizarre scenarios for me. last but not least of which I'm still dealing with is powdery mildew in flower. I have some thoughts on the topic that may or may not be of some benefit to you. First off, I don't believe that eradicating PM is even feasible without a complete chop, evacuate, sterilize and start over, and even then there's a chance you will miss the one spore that starts it all over again. That being said I will tell you what I have done, #1 NEVER spray anything on your buds. full stop. I don't grow this stuff to be dumping something i have no idea what's in on something that one of my loved ones rely on for their pain relief, that goes for baking soda, potassium bicarb, peroxide,,etc... , etc.,, it wont eradicate the pm anyway. The best way for me to approach this beast is to make the environment unsuitable for the invader, with light, air movement, and ph, and temp. Doing this outdoors can be a bit tricky when momma nature isnt having any of it. Here's what i found to be true also, PM has no rhyme or reason,, but it loves the dark little spots that dont get full sun or good airflow, use that to your advantage. defoliate with caution and remember to treat every plant completely and wash up before moving to the next, I use a plant mister to wet the leaves I may want to remove, the spores can become airborne during defoliating and you don't want that, and remember what your seeing on the leaves are the fruiting body of the mildew it means that the PM has been around long enough to mature and repopulate which means you have a systemic issue, now, I know the experts say that PM isnt systemic, but I say that it is and it isnt, its neither, what the mildew has done is to extend its feeding apertures which are little tendrils down into the leaf structures to pull the nutrients form your plant. which sounds pretty damn systemic to me. this also can be occurring on either the upper leaf or the underside, or both depending on which species or subspecies of pm that you are infected with. What i like to do is mist the plant until wet, remove all affected foliage, then very carefully inspect the stem, usually where the branches come from or the leaf stem is where you will often see a faint white or fuzzy spot, I clean all of these with a damp cloth. I have done some experiments this year that I normally wouldn't have done had I not been so damn near perfect with my new cloning technique. and the results are in, the plants I treated this way have done a little better, but some that I did not treat at all that were far enough away from my main grow areas as to not risk infecting them , did better. and it wasn't just one or two. Marijuana plants if healthy can tolerate PM and not affect overall plant health , bud size, or bud density. I have a couple of plants that have all the white spots on leaves and even on the stems, and look as though they are not bothered the least, they are vigorous, healthy almost mature with huge buds and no other problems save for the white spots and some yellowing that may or may not be related to the PM. so,, is this something that as growers we are all going to have to deal with forever? was this a particularly bad year for PM? or all of the above? If you look around in your yard, in the ditch beside the road leading to your house, and at the land upon which your abode is situated, do you see PM growing on anything else? My answer was, holy shyt! its everywhere, so unless you plan on changing into your sterile suit every time you visit your completely sealed and controlled environment grow room, you may experience this problem. And had better equip yourself with the few things we know work. There are some great resources for finding out more about the plant specific Pm that affects only cannabis's or the ones that affect all growing plants online, just google it. not to plug anyone specifically but mother earth news has some great articles about the topic.
This is along my lines of thought.So I’m curious how do you feel about bud washing?
I used Coast of Maine for the first time in pots and also had issues. This after years of outdoors in the garden, with native soil, mostly augmented with cow manure added to the garden soil in the fall and turned again in the spring.
Next spring I'm starting with native soil and cow manure from the garden in the pots. I liked having the pots. Let me turn them a little daily so the plants were exposed on all sides for nice, rounded bushes.
Have a good day.
This is some interesting content regarding h203 and other forms of bio controls.
My COM soil also yielded some yellowing leaves (and still is). COM stonington may be inconsistent in nutes. Same genetics, same treatment all season, bags from different stores have fed the plants differently. I don’t think it really lasts 120 days. I have one pot 60% fox farm and 40% stonington and do not have the yellowing issue.
Some say that in organics you want it to run dry of nutes and that yellowing later (weeks 5-8) is okay. I’m not sure, and am concerned adding pure n at 4 weeks into flower, especially a water soluble N so I have been top dressing build a bloom (2% soluble N 2-10-5).
That said I like the COM soil and would simply enrich it with BuildaSoil amendments. I would hit them harder with N in veg next time with COM.
This is along my lines of thought.
It's commonplace to use h2o2 for harvest washes, especially for outdoor.
H2O2 is definitely effective against PM. I would try applications of that, personally.
It's probably too late for bacterial intervention and things like bicarbs or essential oils can and will ruin your flower.
Keep in mind some mildews are host-specific, some are not
Podosphaera macularis is the most common one to infect cannabis. Its other common hosts include: chamomile, strawberry, caneberry, and hops. Your cucumber or tomato PM will not necessarily take hold of cannabis, so a general treatment of adjacent plants may be in vain.
How is it today?
the strain of wpm that affects marijuana is not the same on any other plants..Less is more I’m realizing. It costs me like $60 a run in nutes and sprays that yields 3+ lbs.
With that being said the pm would have probably have come regardless of any of those other factors. It’s more about the environment at the time. Make sure if you have any house plants near it or in your yard, to get rid of the pm on them too.

Thank you! Another confidence boost that using Dr. Zymes was a good idea. That and the fact that the PM hasn't returned yet. Fingers crossed!Athena IPM 1-2 times a week through veg to week 4 in flower and then switch to Dr. Zymes until the day before harvest. Both product work great as preventative and eradicator for mites and pm. You can use these without effecting look, flavor, or terpene percentages. We test between 3.5-5%
First off - those ladies are prettyRegarding spraying to prevent PM I’ve used Purecrop1 twice so far at about 3 weeks into flower (after finding three leaves with PM that I pulled on 1 of 6 plants) and after 6 weeks in flower a day after plants dried out after heavy rains. So far no PM on any plants.
However I did find minor bud rot on about 6 buds on only one plant (different from one with minor PM ) so those thumb sized buds were cut and tossed.
Today is windy but dry in NE Massachusetts after 2 days of rain and clouds. I also found a caterpillar near bud rot bud so I’ll be spraying all plants with BT this evening or tomorrow morning because I’m hoping to push plants another 2-3 weeks if possible.
Regarding bud washing in H2O2/water mix prior to drying, I’ll do that for budding branches that are less than 18” long but won’t on branches longer than that because they won’t fit into my wash container. I plan to hang large branches for slow dry and will inspect them and shake out “stuff” during dry trim process, which will require burning a fatty while listening to good tunes on noise reduction headphones. Keeping fingers crossed
Im not trying to be "that guy" but didn't you post a thread recently about trying to achieve 2lbs in a 4x4, also being a newer grower? I might have it mixed up with someone else lol.Less is more I’m realizing. It costs me like $60 a run in nutes and sprays that yields 3+ lbs.

Was just trying to understand the cost to return. Wasn't insinuating anything, nothing you said was wrong i didn't disagree with any of it, did i? I didnt see any pictures from your space or anything just saw the initial thread posting.Ya that was me. But if you saw the pics before I deleted them you saw the space is more then what that 4x4 title said. I pulled 3 lbs off a 4x8 on my first grow. Looking closer to 4 this time. Just wanted to see how I can improve. How’s that relevant though. What I said is true.
Unfortunately you are being that guy by insinuating that a new grower is somehow incapable of giving advice. Did anything i said in that post you quoted me on wrong? I don’t think so. So is this just a chance for you to feel superior over me or what? I’m confused
No apology needed by any means. I apologize, I should have worded my post better.Ok sorry for going off. I got defensive. Sometime it seems like people are quick to jump down the new guys throat in this scene. Again my bad
On this note, one hell of a first grow!Ok sorry for going off. I got defensive. Sometime it seems like people are quick to jump down the new guys throat in this scene. Again my bad.
In this case I was the one quick to jump and I should’ve.
The cost of return is actually based on a 4x8 which is closer to 4x10.
HOCL will kill the powdery mold in 15 seconds, just trim away after a quick rinse/wash. Research it for germination/cuttings/fungicide does it all. Excellent for hydro systems just dilute and add to water.This grow has been hell compared to last year, but thanks to the help of @Aqua Man @GrowHobo with reveg guidance, and @Kopper1013 @strider26554 with borer guidance (piercing the stems was sheer genius), I've made it to this point! In addition to that, dealt with spider mites using persimilis a couple of weeks ago, but wound up having to partial harvest last week because of it :( The rest of that plant has to go this week.
And now..powdery mildew. Had to defoliate and remove some buds this morning unfortunately. The only thing I have on hand is Dr. Zymes, potassium bicarbonate, and over the counter hydrogen peroxide. Could either of those help with PM in flower? I have not sprayed anything but BT after week 1 of flower.
Close up pic is of the one I harvested. The one on the left in the other pic is the one just starting to show PM.
