Plants won't dry out

Have a friend using a Peat Based medium Promix Hp i believe it is. He did a 30 day flush on his girls in flower about 10 days ago and they won't dry out. I told him at day 4 if not dry to start poking holes in the grow bags to add more aeration, he did. 6 days later he says they are still heavy and now all the leaves are starting to curl under.

What advice should I give this dude? I told him pull all the plants out of the grow bags and pop them into cloth pots and blast a fan on them but he has like 30 of them going.


Thoughts?
 
He just gonna have to wait it out there just retaining the water prob bcz the lack of bloom nutes with the flush, patience my friend then once he chops toss a dehumidifier in the room. For a couple hours a day.
 
My secondary question would be why a 30 day flush? You or your "friend" could have fed super heavy in mid-late weeks of flower and still you would of only needed to flush 3-7 days.

The only time I've had pots that wouldn't dry out in normal times they had serious issues. Unless it's cold and very humid and in 20+ gallon pots that have crappy aeration properties there is no reason. Maybe a water elf is watering them at night.

Runoff was apparently close to 2500ppm and he flushed them down to 800. Then left for them to dry out. The bottom line is he needs to use a cloth pot or run way more perlite.

I had the exact same issue when using a peat base
 
i'm also using promix hp no added perlite in 5gal buckets and i water twice a weekif i go sunday to sunday they are too dried out imo
 
Get some pics up, the reason mediums stay wet and heavy is due to the plants having issues and not consuming much water. With very vigorous healthy vegging plants you can drench the soil almost daily and the plants consume most of it.
 
I agree my vegging blueberrysourd in vegg about 5 weeks I run promix with 30.% perlite and 10% vermiculite and a shit load mycorrhizae allot of people forget about there roots most likely the "roots" is always the "root" of the problem.
 
sounds like he needs to get them under some hid's along with a lot of air flow. also would let them go almost completely dry before the next watering.
 
Your suggestion to put them into fabric bags would help out. Are there sufficient drainage holes in the existing bags? If so, sounds like the soil/medium is too compact. ProMix by itself is too compact for good drainage. pumice, vermiculite or perlite should be added for aeration/drainage. You have to start out with a medium that will retain enough water for the plant yet allow the excess to drain off and allow the roots to dry out between waterings. The lack of flowering nutes has nothing whatsoever to do with the retention of water. The plant will use only what it needs, and the rest needs to drain away fairly quick.
 
Tell your friend to next time water just enough to keep the plant in oxygen instead of complete saturation.

I'll take a guess, a number of medical growers do what's called 30 day or so flushes. But these are not the same as dumping 5 times the amount of water as the container size. The drowning your plant method is a medium correction for imbalances or more often too many nutes used over time.

To the OP:

I use Promix, if anything it dries out too quickly for my liking...so I add worm castings. Your friend must be using very large grow bags, try using more fans from different directions to speed up evaporation.
 
Thanks for that not on the lack of flowering nutes I had an arguement with my friend over the same thing I told him that the lack of nutes should not make the plant retain anything asit uses only what it needs as u stated he owes me 20 bucks now :)
