rust spots on leaves

ok so here is my system breakdown

3rd week veg
1000w hps
AN gro micro bloom ( 4ml. per litter )
FF root drench and micro brew
cal/mag ( 20ML per 5 gal, just suplementing for the low dose in the AN )
room temp 73
rez temp 64 day and 62 night

so i am noticing "rust spots" is the best way to describe them only on 2 or 3 leaves the rest of the plants are verry healthy they have been there for awhile but seem to be getting worse, no new leaves seem to be affected im thinking ima just keep moving forward but if i am missing somthing and its some kind of deficency i would really like to know . here are some pics and thanks for the help

ok having trouble uploading pics i will try agin in the morning

If you are using ro water you may need to up the calmag. Ph would be first place to start

What's your Ph? Check that first if Ph OK than likely Cal or mag issue but need pix.

Without pics, we can't help much, but here's a start.View attachment 2539511

4ml/gal sounds like enough calmag for 3 weeks into veg

I would start at your PH

ok so i failed to mention i am using AN PH perfect grow micro bloom and RO water. still cant seem to upload pics but im goona keep trying, i click manage attatchments and the screen pops up but stays blank.....anyway thanks for all the help and im gonna figure this pic issue out soon

heres some pics of the spots,,,no more have shown up and i have since cut the affected ones off, just wondering if theres anything to worry about since i have never had this issue before? ,,,,,,,,thanks for all the help

You still have said nothing about ph which is crucial. It could need more calmag or be a ph issue.

Sounds like PH if its that bad with 4ml/gal.

Looks like magnesium to me. Does your PH get past 5.8? Mag isn't available until that PH.

And yes there is something to worry about. Magnesium is one of the most important elements next to NPK. It is essential to photosynthesis.

from what I understand, you don't want to mess with p.h with the p.h perfect line. My guess is more cal/mag to make up for the r/o and low amount in your nutes. you also have some purple in the stems, also an indication of cal/mag def.

Fuck that. Ph is the most crucial aspect of hydro and i would not ever leave it out of range no matter what the nutes.

I have read of people causing a bigger problem by trying to adjust that p.h perfect stuff. Not a nute I would use personally,I like to have control of all that. But that stuff works different.

ya i am using the AN ph perfect and they said for NO reason should i even

think about adjusting it so more cal mag it is and i will update in a few days thank for the help everybody

you might want to water with the cal-mag and nutes seperate, cal-mag causes p.h to lower and sometimes doesn't mix well with certain nutes, Not sure what An says about mixing in cal-mag with the An ph perfect line, but you should find out.
