Yeah, so my problems still continue on.

I don't feel that it's underwatering, I've been watering near daily for the past week(yes the soil is near dry by that time) ((troubleshooting))

So it's either fungal or it could be something nute related...possibly some over-fert action.

I've completely sprayed the plants w/ a .04% sulfur containing fungicide type spray.
Apparently it works by adjusting the leafs ph out of range for fungal foothold.
I also pulled every leaf that had any sign of anything on it.

I really don't think it's fungal, but it's always possible.

Basically the leaves develop the lil rust spots, purple upper-sides of stems, then they gradually dry out as the rusties develop. Eventually the whole leave is pretty dam dry...this usually beats the complete rusting of the leaf.

I've begun to think it's overfert of some sort...would make sense about the leaves going so dry.


I've also raised the light and increased intake along w/ extraction.

So hopefully this'll be the end of my problems and my 5 point attack will take care of just about every possibility.


I also flushed a few gallons of water through the plants, incase over-fert is the problem. I'ma not feed em for awhile regardless of whether they look hungry or not.

Lemme know what y'all think the likely culprit is.


P.s it's not just the top leaves or the bottom...it's kinda randomly spread throughout. New growth is nearly never affected.


Cheers y'all!

Then your environment is not right or your pots are too small

Owd

are they only drying out at the top, do you check the weight of your pots to see if they need feeding, maybe just spraying the top of the soil would be suffice.

its a fungal infection, sulpher is unlikely to cure, it may help a little.

Same here Jasper, seems to be comon these days...

Yay finally the pro's are here!





Yeah, I figured that near daily watering wasn't a good thing.
The RH in there is 40% though, temps between 75-80.
Could just be that the air coming in is mega dry and they're struggling to hold water?

What would you recommend I do to fix the environmental problem?

The temps are solid, I could lower extraction...but wouldn't that be unwise assuming OT is right about the fungal infection?





Yeah I typically wait until they're nice n' light. It used to be that the top would dry out way before the bottom (hence why I added perilite to the top, which seems to help)
Now the whole pot gets perdy dry b4 I water.





What kinda treatment would you recommend OT?
i.e what kinda active ingredients would I be seeking etc..?

I'm on the other side of the pond, and unfortunately my hydro shop doesn't carry any Plant Magic products (looked for essence)

Is there a strong correlation between fall and indoor fungal infections?

I'm assuming this got a foothold because the environment's off like Owderb said? Any recommendations on fixing that?



I really appreciate you folks stoppin by to help. ALOT.

Oh no!
I see the purpling uppersides of the stems. Bummer!


Would the mycrorrhizae I'm using potentially be the cause?

To see what's not in my profile... http://www.uk420.com/boards/index.php?showtopic=195215

So I tried a product called "actinovate"

"Actinovate biological fungicide uses the beneficial bacteria, Streptomyces Lydicus, to control soil-borne diseases including pythium and fusarium as well as foliar diseases like powdery mildew. Use Actinovate as a soil drench and you'll also promote healthy root development and improve overall plant strength in addition to combating soil pathogens as the spores germinate and colonize the root zone. Each 2 ounce packet treats 550 plants or 5000 square feet. 100% soluble, Actinovate can also be used as a foliar spray. "

Doesn't seem to be working at all.
Actually one of the mothers is looking pretty healthy now, not sure if it's attributable to the crap though.

It's killing me, every single day alls I do is tear off foliage. It used to be count the new leaves and be blown away. Now it's just tear it off tear it off.
If the plant doesn't turn around in the next week or so I'm just gonna scrap all the poor looking ones. Frustrating, and shitty to waist a month and a half but oh well.

Why not use Essence mate its be rated good by growers here, http://www.uk420.com/boards/index.php?showtopic=147113 i was told it had good effects on leaf fungal infections.
I also have fungal problems but that products are not availeble to me but if i have it i would not think twice to at least try.

I had the beginnings of LSF on my current plants which started in week 1 of flower, I treated them with some PlantMagic Essence which has totally stopped it in its tracks, I am just coming up to week 4 now and my plants are doing brilliant and there is absolutly no sign of LSF on them.

I have to say Essence does seem to live up to the hype, I am very impressed with it.

I can't seem to get any PM products here. (I'm in North America)
Otherwise it'd been essence right off the get-go


I think I have a plethora of problems though. I feel like writing it off as just fungal would be silly.
I'm near certain moisture stress has had something to do with this.

I'm looking forward to doing a rebuild of the drobe aswell. Loose mylar is lame.
I'ma make a slideout shelf where the pot bottoms sit through aswell to make watering and whatnot easier.

Still not exactly sure where I've gone wrong though

same here we should start a petition for global delivery

then sit and pray that fungus goes away just like me

no doubt.

Surprises me that they haven't setup shop here in the states. Essence alone could make a killing if it's as good as they say it is, which I imagine it is.

Maybe we should open up shop Start importing hehe

What exactly is this supposed to be? The purple stem thing. Cos the best plant I've ever grown had a purple stem all through the grow. I noticed her from seedling by the stem too. All the others stems were like a clear, transparent lime colour. This girl had a burgundy stem. Jiffa mentioned he thought it wouldn't get through the grow but it turned out to be a corker. Best plant of the lot by far. Smoked a treat and looked just as good. So what exactly does a purple stem indicate? .... and I know for sure you can have a plant with purple stem and get a high grade smoke. I put it down to difference in pheno. I'm talking main stem here and bright red fan leaf stems. I've had numerous plants with red fan leaf stems. Only the one with the whole stem all colourful.

I wasn't meaning all purple stems are bad..or anything like that, not sure if thats how you're understanding what I was saying
some pheno's and geno's have purple stems, as you well know
Not like it's some indicator of a universally terrible plant...

Just resembled my plant in more ways than just the rotting leaves is all.

I assumed that the purpling upper sides of the stems was part of a deficiency or disease in our case.

I think it's a sign of some sort of deficiency when it's just the upperside, but I'm honestly not sure. If I did know I'da cured it by now hehe


Feck I can't even water my plants proper, prolly why I got into this whole mess to begin with.
