Rusty looking Spots on leaves

[BubbaKush]

G'day, I've got rusty brown colored spots that have appeared in the last 3-4 days I've not had this prob before, I backed of the nutes 2 days ago to 1.4ec when i first noticed some clawing and a few spots but it's seemed to spread.

 

Plant: Ak47×White widow

Nutes: Canna coco A+B, rhizo, cannazym, bud candy to feed bennies, rhizo and cannazym only once a week.

Just started great white.

Tap water airated with aquarium pump for 48hrs before use •04ec.

3•5 weeks into flower.

All seems good

 

give it a flush?

[BubbaKush]

Just got cal mag and silica on eBay, moving back up to the NT soon and will be using RO boar water and rain water in the wet.

 

Will the silica and cal mag help now? (Vic water)

[BubbaKush]

I dropped back the nutes and flushed 3 times getting 1.5ltrs run off each time.

 

Should I do a flush with sensi pro crystal clear? I have that on hand

[pedro de pacas]

Nah its flushed enough, might be using to many additives, something might be clashing with something else ?

dunno don't use them

 

use a bit of ryzo or seaweed when there young, PK when there flowering, and the same  A & B all the way through 

 

need better pics, to have a better idea

Yeah OK I hear ya, I'll just use the a+b and pk from now on.

I reckon your right, this is the first grow that I've used the other additives on and the only time I've had this problem.

Its all lining up and making sense now, thanks for your help I appreciate it!
