Is this mold?

[gigimarga]

My leafs just went droopy and there's some sort of white stuff on them. One of the leafs feels dry.
I misted the soil this morning and it feels moist under the top part.

Whoa....something went terribly wrong here....

Fill out the troubleshooting form....

My guess is too much soil and too much moisture.... What size pot(s) you using???

the soil looks like it has alot of wood chips ect. Could mean acidic ph. I have had good luck with scotts premium potting soil. just add a little perlite. the best commercial potting soil i have used is the southern states brand, comes from factory with extra perlite and it seems to have what cannabis like in it.Some say MG is good to , but never used it. But fox farm is the best.

That plant ain't gonna do much more but,die.. I'm sorry to say. The tap root is tapped-out. It's been burned in that hot soil. I'll bet the ph is off the charts in that soil.

This is some of the worst news to hear,I'm sure. Just trying to save you some frustration in trying to save such a far gone plant..More beans would be in order at this point!

This was no burn soil with very low nutes, about 30% perlite which I flushed prior to starting it. It was at all times in a dixie cup. I can't think of anything I could have done better.

Moved some of the top soil around and found that the roots still look fine. I think I might just have to give up on soil. Nothing good comes of it. Maybe this strain is very soil sensitive but I doubt. That white stuff is like dust.

If it doesn't recover after spraying it with backing soda water, I'm going to do the next auto WW in hydro.

The hydro bucket started growing rice from probably a grain that fell in the Hydroton Clay pebbles from some Chinese worker's lunch so I know it works much better than this.

PH and TDS are also much easier to control.

Hydro is a VERY different beast.... But if you're confident about it, go for it!!! I myself can't wait to start hydro again....

But from personal experience, I'd suggest at least one successful soil grow before starting hydro.... Why??? Because hydro is waaaaaaaaay less forgiving than soil....and if things go south in hydro, you might just give up....and we don't want that do we....

Have you filled out a troubleshooting form??? If you haven't, fill one out so we can see where you might be going wrong....

Here is my advice. Shelve the soil and nutes you have. Buy a bag of fox farm ocean forest and some seedling mix - sunshine mix 4. And use that. It is just so easy. What strain are you working with again? Get something that is easy to grow this time - just about any kush, big bang, lemon skunk, something that will be forgiving. That was the key to my first successful runs b/c god knows those poor plants never should have survived let alone produce significant product! Perhaps you have good chemistry skill but otherwise, hydro is going to piss you off. Screw it up at any point and you will end up with a bucket of slimy roots. If you go hydro do lots of reading! Keep with it. It just takes a bit of perseverance.

The auto blueberry I'm doing in hydro has developed the same white dust with droopy leafs and yellowing after a couple of weeks. The roots look beautiful. The temperatures got to about 85-88 for about 6 hours so it's probably a source. The white powder smells like cheese.

I tried the dishsoap/baking soda/RO water/vegetable oil spray to remedy the white dust and hopefully it will recover but I can't tell if it will help.

Does anyone have any ideas or suggestions?

The PPM is about 200 and Ph is 5.8. I adjust the Ph on a daily basis.

Two growing methods....same white dusty powder??? Is there anyone else with access to them when you're not around??? Just want to rule out the possibility of sabotage....

Curious....where did you come up with the dish soap, RO water, Veg oil, baking soda "remedy"???

Any possibility that something you are spraying on them is creating the white powder???

What hydro method you utilizing???
