What causes PM

This is PM? Guessing entire tents contents are toast? Got 14 plants to pitch ugh my entire last two months of work gone like that!

Iā€™m sure someone knows how to save it. Itā€™s not a lose. Iā€™ve never had it ever.

Since ur still in vegā€¦

Someone just told me it looks like salt build up.

Thatā€™s not PM. Maybe another mold but not PM, looks more like just a little mineral crust.

Many many ways to prevent it and cure it. Cures are a contentious topic so Iā€™ll leave that be.
Plenty of threads here on it. Keep your humidity under 60% past early flower, keep airflow always high, both extraction and circulation. Avoid introducing it.

If you run conditions conducive to it, you will get it, so donā€™t slack. Air quality is just as important as light and nutrients.

looks like salt build up. Not mold. You said your running coco so I assume youā€™re using liquid feed. Your drybacks are going to far and causing salt build up on your fabric.

If you had PM to that extent itā€™d be all over your plantsā€¦

If you ever run into a PM problem I highly suggest Hypochlorous acid. Stops it dead in its tracks just do a foliar. I happen to use Athena Cleanse at full strength if it happens but there is a $20 1 gallon option on amazon that is 500 ppm just diluate and save some cash.

little flush and wipe. I being sarcastic you donā€™'t need to wipe the pot. :rofl: You should think about canceling your trip. kidding. :rofl:

Also I fed for the very first time using megacrop on the last feed I did before going z72 hours without water. Then I watered tonight came down two hours later saw thatā€¦ any chance I ā€œflushedā€ the megacrop out and it saltified on the bag?

Not PM. Donā€™t worry about it.

Practice good air hygiene.

If they dry out for two days so be it I wouldnā€™t even worry. Not ideal but no big deal.

I let them dry for 72 hours to see if I could get by on vacation with a friend only stopping by once. Normally I water less but daily.

I donā€™t trust other people to mind my grow but Iā€™m a megalomaniac. If someone can water for you thatā€™s good.

!!! Thatā€™s it amen!

the roots at that size in that pot maybe had too much water and couldnā€™t drink all that was given,that has sat laden and trapped in the medium with nowhere to go but start moulding because nothings drying itā€¦a sort of example to others here when you overwater the effects can cause havocā€¦not unrepairable as the plant looks healthy,but leave as is and further along the line it will eventually stick inside your root column to flower sites and promote a rot of the flowersā€¦Iā€™ve quoted for years that pm and budrot all starts with mis management of wateringā€¦budrot starts from within the heart of any flower and works it way outward,systemic with the water column being choked internally in the bud columnā€¦pm is the early signs of what eventually turns rot in flower if you donā€™t remedyā€¦

I wouldnā€™t call that a terrible salt buildup, if it indeed even is. Could be just a few spots of mold. Mold likes wet conditions, hard to say from the photo. If you are using organic additives itā€™s almost guaranteed. I have grown in very hard water and salt crust is more or less unavoidable. I try to read the plants more than anything. If the plants are happily growing as well as they can, thereā€™s not a cause for concern.

They seem happy! Iā€™m gonna let it go. Wonā€™t even wash it offs guessin itā€™ll eventually was h away

Just search hypochlorous acid itā€™s a white gallon jug and is 500ppm.

You donā€™t need to worry unless you plants start going south. Just let it ride and try to maintain your moisture level in your coco donā€™t let it get too dry.

Also your RH is way to high imo. But then again I donā€™t follow VPD for shit. I think itā€™s malarkey. lol I like to keep my rh around 50% give or take. I prefer non mold causing conditions and lots of air flow. My plants usually seem happiest this way.

I feel that. Iā€™d rather harvest slightly less than lose cola after cola to rot. 50% is a good number to shoot for. I further think VPD better applies when you are truly ā€œmaxing outā€ ie using CO2, active hydro, etc. Itā€™s just not a limiting factor otherwise.

This a great word I really enjoy. Rigmarole is another good one.
