Greetings,

A friend of mine... has asked me to ask you....

Does anyone have an idea of what this problem could be, as depicted in the photos attached. My friend, says it could be phosphorous deficiency, but he is not sure.

I agree with shottafire. Looks like insect damage.
Can you get magnification on the underside of those leaves to look for mites, etc.

Bingo I believe we have a winner. Give this young lady a cigar.
Winner winner chicken dinner.
I do believe she is right on all counts
Black dots would be the dreaded insect poo and the light colored damage to the leaves is where they have eaten there way through your plant.

Re: Need help from the gurus...

You may want to check out a product called Spinosad. I have read where they use it on certified organic vegetables.
is the above said plant in Veg or flowering stage?

Greetings again.

My friend did a better inspection, and found these tiny little bugs. Green transparent wings set into back like a peaked roof. Narrow, they move fast, but seem disinclined to fly. Body very flexible. Black eyes bugged out from side of head...photos below. My friend said he did his best with cheap camera and cheap magnifier.

Greetings,

I want to thank everyone for their input on helping us solve this problem.

So is there a consensus here as to what bug killer, commercial or otherwise, that he could use that is organic, non toxic, effective and permissible for use in flowering stage ? While being available in Europe ?

are you seeing any signs of grey trails on your plants? also what phase of life is your plant in? If it is Thrips you will need to treat your soil as well as your plant since they can live in both.
 
Thrips. I have suffered at the hands of these little buggers. I used a mix of neem and rosemary oils, a drop or 2 of soap and warm water. I hit my plant hard with a sprayer at lights out every 3 days for a couple of weeks.
These were mine

Re: Need help from the gurus...

You can use Spinosad for Thrips as well as leaf miners and it is completely safe to use during flowering stage. Keep in mind that when you do your treatment you will need to treat the foliage AND the soil at the same time. It is a bacteria that is only harmful to insects and not to humans or animals.

Well Doh,
I am new on this site and keep forgetting that not only do we pretty much have growers here that can pretty much answer any question one could possibly come up with but we have sponsors that pretty much covers the whole spectrum of needs for every grow situation.

I am blaming it on the fact I am OLD

I have read this, could you provide more information ?

"Several hundred lozenges at Mountain High were quarantined after inspectors found their labels listed the pesticide spinosad, an insecticide that is slightly toxic to humans, according to Dan Rowland, spokesman for Denver's office of marijuana policy."

And Spinosd is not listed on this directory of safe pesticides for marijuana use.

I am not trying to be a tool, I am just trying to help my friend as best I can. Thank you for your help.

Could you provde me the ratios of water, soap, rose oil, and neem oil that you used ?

Once again, thank you for your help

I do note that both Neem and rosemary oil are on this list of approved pesticides....
