hi If you have a mildew colony, here’s how to wipe it out and make sure it never comes back.
Mix 1 tablespoon of 90 percent plus sulfur dust with 1 liter of water, then spray that on all of your plants. Do it again 2 weeks later, and then you can start bloom. Never, spray it on blooming plants, because that’s gross, unless you are just making seeds. Also, never apply after an oil based product, you will have to wash that application off first, then apply the sulfur.
To ensure it never comes back, just don’t bring any infected plant material in. It’s really that simple. Keep new cuts in quarantine and microscopically inspect them daily if possible. You can see the infestation way faster with magnification!good luck. 8-)

I use captain jacks neem oil twice a grow once during veg once right before flower. Always turn my lights off after long enough to let it dry. I haven’t had a pest problem at all since using this. But as I’m writing this panic has set in as I don’t think I’ve sprayed my current grow at all annndddd they are already in flower.. oh my bajesus😂😂🙈🙈🙈

We had a few leaves showing signs ( growing outdoors in poly tunnel), sprayed just the fan leaves with milk/water solution, believe it was 70% water/30% milk mixture, stopped it in its tracks with no further signs.
Also tried using it on plants in the garden and it was successful on those too.

hi if your lucky and have the right type just shifting the ph out of range (which is what the milk does)can kill it off,however the type is not often the same on cannabis for instance to be honest there lots of various types and thankfully in the uk we do not yet have all of them regularly turn up but all the time we import plant matter from foreign climes we also bring new pests and diseases.
the sulphur seems to work on all the types we have local to me and a saviour of my tomatoe crop this year as it started real early and i missed it and had nearly binned the lot.
we have a horrid type of blight this and last season damages mainstems and plants slowly die of starvation it seems immune to copper or sulphur and even roseclear failed to kill it.
bin for about half my tinas cacti :oops: sad as some was old.good luck

hi cant hurt i do spray if i remember in the drobes between crops,make sure not to spray sulphur in the near area of flowering plants as it can impart the rancid flavour to your weed,i found this out the hard way,yuck and only fit for oiling.
the worst culprits for spread of pm is weeds in your patch and anything like clones etc you bring in can carry pathogens of allsorts i have a quarantine area for clones and they go through a dip in pyrethrum and a copper spray and if they survive that there good ones.peace
