1 mo. into veg brown spots all over - only some plants

Hi guys, so I'm currently a month and a week into veg and a few of my plants are starting to show some problems.. they all look the same with these odd brown speckley spots.

Im at a loss here because its only happening to a few plants (all plants are bagged so they're random strains)

do you guys think its time for a good ol' flush of the soil?

what water are you using, what nutrients are you using, how much, how often?

regular tap water + calmag for REGULAR WATERING ph 6.5

regular tap water + calmag + fox farm grow big (3tsp/gal) for FEEDING ph'd 6.5

I alternate feeding and watering.. and i find myself watering these <1gal pots every 4-5 days or so?
I know its not over watering... could be over fert i suppose though.


growing in FFOF soil.. CFL lights nothing too complicated

yeah, probably don't need the cal/mag when using tap. have you checked your tap PPm's, PH and do you check those before giving your plant water?

the calmag was definitely needed before, as i had a ca-mg deficiency.. do you think i should just exclude it from my WATERING time? and only water with straight Ph'd tap?
I know my Ph is correct, it comes out the bottom of the containers 6.5-6.6

and PPM's.. Im not very concerned with since my nutrient combo is so simple (and my city has some of the highest quality tap in the US)

comes out the bottom doesn't mean anything. going in is what matters. I would cut down on the cal/mag for sure and I would also concern myself with PPM's

lol.. i just said i ph my water to 6.5 and it comes out 6.5-6.6

I think you might have a potassium deficiency.
