White dust like scale on fan leaves????

I am a UK grower on my second grow under 600w HPS in soil and terracotta pots. Using Nitrozyme and Plagron green sensation and alga bloom. Had a fairly succesfull first crop.

I noticed on the first grow and have noticed on this grow too that the fan leaves look dusty. This "dust" will not brush or wash off. It is difficult to see under a 60x scope what is the cause, just looks like white blobs. It seems to be more widespread this time.

I have tried to take a picture but without success so far. I will post my best effort so far in my next post.

Any ideas would be greatly appreciated.

Thanks and keep schmokin!!!!

If it is mites, a good thing to do is to buy a 7 in 1 sprayer nozzle....
Spray them down (thoroughly) with an insecticidal soap and take them outside and (thoroughly) spray them down using the different settings (some leaf damage may occur, but is minimal and the plants will recover).... this should lessen the population and remove a great portion of the eggs. Then spray them down again with the soap. If you have a blender handy, blend 4 large habanera peppers in 2 cups of water and strain into a pump sprayer ($10) at Lowes. Mix in 2 drops of dish soap and spray plants and grow space. (you may add up to 1 cup of plain water for more mix) This mix is amazing.

Thanks for all the positive ideas. Nothing is visible on underside of leaves.

Pharmacan- will check out that info thanks.

Oh god i hope its not spider mites. Will try to get a better pic tonight.

Olddrifter66- lets hope that wont be necessary

Plants appear healthy apart from this.

Just got back from work and checked the ladies, and unfortunately its definately spider mites. Had a CLOSE look at underside of leaves and there are little black bastards crawling around everywhere. Guess i am about to learn a lot about the little f*****s.

Sorry about the crap pics - didnt really help the diagnosis, must get a better camera for close ups.

Thanks for pointing me in the right direction.

I was just coming on here to post about something similar. I hope its not mites as well. What I'm seeing is circular, white patches of dusty looking material. Some of it will brush off but it seems like a little is stuck to the leaves. It looks different then whats posted above. The spots seem to be around the size of a dime or smaller and more prominently white but they are showing up on the fans. I checked out the bottoms of the leaves and I didn't see any mites. What else could this be?

Yeah that dry white milkish looking film on the bottom of the leaves is a tell tell sign you have about 5 days max depending on temps, your garden will have webs and infested with these creatures... I had to shut down because of it. I wish you well, some mites go easy, some not.....

Next time try to post your own thread... but it sounds like Powdery white mildew which is almost equal as spider mites in the eradication methods. There is a thread in here somewhere that explains this horrible Fungus. Sulfur Burner is what you want. Good luck.

Like SCF said, you have only a few days before these little bastards magically multiply. Im sorry you have them, but now is your best chance to avoid a total infestation. I have used this method twice in different locations, and it worked, but I am no guru by far. I got the method from a botony student at the local college and it works. Good luck. Keep us posted.

Anyone have any suggestions as to how to get rid of the little buggers.

Have heard a lot of good things about AVID and FLORAMITE. Are these available in the UK? If not what can i get in the UK that works?

Olddrifter66 - what is an insecticidal soap? Also dont know if i can get Habanera peppers in the UK.

Thanx in advance

Thanks olddrifter66. Picked up a spray from my local garden center last night. Pyrethin based, with rape seed oil. Hopeing this will do the business. Have also ordered some other products off the net which i will use in 7 days (once they arrive), for a double whammy effect.

Intending to have a 2 week break at the end of this run, and give everything a good clean.

peace

NOW IS THE TIME TO ACT

NOW IS THE TIME TO ACT

my regiment for mites:

spray down each plant with FF's DontBugMe

repeat 2 days later (70% will die)

2 days after... spray down all plants again with jus plain tap water then introduce predator mites into the garden (100% death):violin:

gotta order the predator mites 1st cause they take around 4 days to receive
