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

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 :x)

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 :P

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:)
