any ideas any1 ?

hi guys
does any1 know wtf is going on with these plants ?

or even better how 2 solve it lol here some more pics

Check the undersides of the leaves for anything that shouldn't be there, it looks like the start of a spidermite infestation.

ive already checked mate
i think its a diff in something

also the leaves r turning yellow with brown ptaches

do u foliar feed the leaves at all??

no i never spray anything on 2 the plants
there on a recirculating system

Sounds like a Magnesium deficiency with the brown spots. Do the leaves curl upwards before they die ? And did it start at the bottom of the plant or the top ?

i think there curling down mate
and yes it started @the bottom and is working its way up

ive just been 2 check and yes they r curling up ?
heres another pic

any 1 else have a suggestion?

geniuely looks like spider mites, i use blockout, a organic pesticide or neem oil. good luck!

i dont think its mites
they wouldnt b killing the plants
i mean mites doesnt explain why the bottom of the plant is turning yellow and brown

Maybe you have more than one problem. Get a magnifying glass and look for mites and or webs. I just picked up a product from General Hydro thats organic and its really easy to use. It's will kill them and keep them from returning. It's called Aza Maz. Goodluck

It will kill them...

surely if ihad enuff mite 2 do this kind of damage the would b on all m plants
i have about 28 plants and only 4 are affected ?

im thinking dr indcia's right from what i can see in other psts it looks like mg diff
im gonna get some lime 2moz will keep u up 2 date

im sorr what will kill them ?
the mites kill the plant or the spray kill the mites ? lol

spider mites eventually kill marijuana, they spread from one plant to the next so no they wont be on all the plants yet. thats not mag defientcy causing the white spots, the spots turn brown after a while because the leaf is being sucked dry from the mites. look with a micro scope and have a look at the little pricks! peace
