Help! - downy mildew. Physan 20 substitute needed

Hi every1.

1st time grower. Got a few lemon haize and cheese plants just past the 1st week of veg.

I have noticed that some of the plants have downy mildew.

I cut back all the affected foilage, but as you can imagine it has returned 2 days later.

I now suspect this has been caused from draft from the inlet fan blowing directly on the plants. I have made adjustments so this is no longer the case.

Humidity is around 30%.

Plants are touching eachother but there is nothing I can do about that :(

I will be lollypopping them at the end of the week so this will allow more air flow. (will maybe do this earlier if the DM gets out of control)

But overall I would say airflow is ok.

I am using canna coco preffessional as medium & cana coco A & B for nutes.


Anyway, I have done some research and discovered that Physan 20 is a great treatment for fungal problems but I can not get it where I am located.

Can anyone suggest a subsitute?

I have read that SA-20 is exactly the same but I can't get that either.


I have also read that this is another solution http://mistralni.co.uk/products/c10-c16-alkyl-dimethyl-benzyl-ammonium-chloride-ba but there is no information on application or any information saying if the person had used it, so I am not willing to purchase this if I dont find people saying they have used it on cannabis.


I have also read that Selgiene & Selgiene Ultra would work but again, not got much information on this and the sites I read this on where not cannabis sites.

Has anyone used Selgiene or Selgiene Ultra? If so, did it work and did it damage your plants? Also, what dosage and how did you apply it?

If anyone knows any other ways to treat the problem I would be very gratefull to hear them.


Thanks

Oh, and one more thing. Are the above mentioned products ok to use with my nutes as a drench & as a spray?
