Hey stoners, just been to see me mate as he has had a wierd problem hes never seen before and its got me stumped too. In his res/brain(same) tank he has these little white worm like bugs(very very small) that skim across the surface of the water the same way that mosquito larvae does.I guess the only difference is that these are ON the surface and not below like mozzies. Anybody know?

Help!!!! Picked today and right in the centre of the top bud is mold - white (looks like cobwebs) and in some places it has started to go brown - what can I do??? Do I have to throw the crop? Is it salvgable?? If i smoke it what will happen? does anyone know anything about mold and the difference between FUNGI and MOLD??? The crown bud was larger than a beer can, but when cutting the individual buds off, white, brown and even purple web like matter was noticed. I have salvaged what I could, but am still concerned about smoking it. BLOODY HELL. This is my first ever crop, and I have definetly learnt many things already. Dissapointed, as I managed to get rid of the spider …

Just checked my plants and it looks like there's really fine webbing over the tops of some of the big buds, and in between some of the leaves. I checked under the leaves and it looks like ther's a few tiny brown crawly things under there. Last couple of weeks the leaves have been getting white spots on them but I can't see any bugs flying around inside the cupboard. I've got 4 plants in a cupboard, run to waste, 6 weeks into flower. I've just sprayed with white oil. Anyone know what it is or what else I can do? I took some pics but you can't see the webbing. Any help appreciated, they're almost ready to pull!

Arrgh, I think I have scarid-fly!!! 1 2

Ok, So I don't have Spidermite, I'm pretty sure they're scarid-fly, but I have these tiny little white things crawling over the top of my plants in potting-mix. The plants themselves look perfectly healthy and are growing strong, but I'm concerned as to what these little things are. They are "jumping" across the surface of the medium - I assumed from this behaviour plus the fact I dug in the mix and found a tiny little flying insect that they are scarid fly. Fortunately, the plants are watered with Dutchmaster Guardian - I believe this will help? I just gave them a good spray-down with a pythreum/garlic spray I bought at the nursery, will this do anything? I do …

A problem has started that I haven't seen before. It looks like rust. It begins in the main veins of relatively new growth, killing the leaf from the inside out. Older leaves are not affected as much as the newer ones. It is especially apparent in the tender newest leaves trying to grow from the tops. It halts the growth of the plant, as it struggles to survive against this problem. What could it be? It's affecting nearly all my indicas, but not my sativas, even though they are planted together.

Hi, I have this problem with my leaves. The room is and has always been very well ventilated and by looking at them it doesnt seem to me to be any kind of mite or bug. Ive been having murders keeping the PH levels right and over the last week they have been subjected to high levels almost constant could be the cause ? Indoor hydroponics, White Rhino. I hope the pics can help, the green is really more green and the brown isnt so rusty colour on the leaf. Also the the leaf is curly upwards and very brittle and are starting to look like this as soon as the new leaf starts to grow.
