How much are you feeding and what is your cal/mag strategy?

--Autos in Ocean Forest and Smart Pots.
--Feed very lightly (half dose of FF nutes) maybe once/week.
--Water every other day, lately.
--In Week 11, but it's my first grow and I had a slow start.
--I have not used any Cal/Mag products.
Sounds like a calcium deficiency perhaps? Thanks.

Is Cal/Mag safe to use during flowering?
I've tried to test the soil several times and always have trouble deciphering which colors line up. Everything appears to be in the right zone (ph hovers around 7 with my instant stick tester, but a little less on the rapid shake and wait ones). I read dolomite isn't good during flowering because of potentially too much nitrogen. I'll test again today and see where I'm at. In the meantime I'll grab some Cal/Mag to have on hand.

Are these plants outdoors? It looks like leaf hopper damage - http://www.growweedeasy.com/cannabis-leafhoppers
ca/mg deficiencies normally start to look like rust "blotches" of odd shapes. These are all round dots like the ones left after a leaf hopper has sucked out the chlorophyll.

I was thinking how odd the symmetry was for cal/mag too. Not saying it isn't , but at the very least odd.

a picture of the entire plant would be good
looking at the one leaf it looks like a bit too much N and calcium def
FFOF soil always goes out of calcium quick and the foxfarm nutes don't list % for calcium (if I recall correctly)
so that adds to the potential for calcium def
but again its not really good to try and diagnose based on one leaf a picture of the entire plant please
only thing else it looks like ot me is ozone damage if you got an ozone generator going... im not good with bugs thou so I cant say with certainty its not bug related but too me it looks like calcium def from the red/rust freckles

to my knowledge dolomite is calcium and magnesium / lime and a ph buffer
does it have N? I don't recall it having N
im not sure id add any if your ph is already 7
gypsum might be a better organic choice for calcium but itll take a bit to become available
you could add a little gypsum (maybe 4oz per 7.5 gallons) and supplement with calmag until it starts working
and then get your magnesium from Epsom salt if you need it
but im still new at the organic stuff so.............. maybe check with someone whos better at organics than me if going that route
