fungus flies, black spots on leaves

leaves die off, go yellow, worse at tips, and tiny black spots all over leaves, and blotches on some leaves same as tips go

Over watering much? You may have root rot. How often are you watering?

usually every 2 days, its not overwatering

Look at this. It is not real good but sometimes helps.

What is your setup? Soil/Organic?

the problems in 2 grows, was leaning towards nute deficiancy for room 1, but the other grow has had if anything too much nutes and same problem, theres was some flies knocking about aswell

looking at the link tho looks pretty much like potassium defiecency

should mention they are both in veg

Click to expand...

both in coco

bad bad infestation?The gnat's larvae will eat so many roots that the plant can't get proper neuts.

Coco I know what that is....ask boneman ....he has a coco thread.

was lots of flies now in one a few, in other havent seen any for about a week

ill take some more pics if i can

took some more pics..

You have bad coco problems look for a coco thread and ask there too.

god damn flies are back with a vengeance now

im fairly sure its the larvae fucking the root system


i sprayed a week or so back and thought they had all gone, but obviously more are hatching from the coco...


what can i get to treat the coco aswell as a spray


(starting to think this crop is fucked and i need to start again, with a nice sterile room, shouldve been in bud 2 weeks ago now but havent seen the point with how ill they are )

even my clones are screwed now aswell, its as if the coco ive used was full of larvae to begin with or something

Sorry to hear that. Coco was so hard for me...Like hydro with dirt:0

thing is ive grown in coco for about 4 or 5 years, never had anything like this before....

never had those type of flies before, had a bad spider mite infestation a year or 2 ago from some bad clones, cleaned them out and have never seen any since, fingers crossed i can do the same with these little bastids

BTI or bacterium thurginesis isralius. Commonly called BT or mosquito dunks. The liquid is better. You will have to treat more than once. Sticky traps will catch some of the adults. Somone may know a chemical method
