What is wrong with my outdoor plant?

Hey whats up guys.. So im about 2 months into veg and 2 of my plants are showing signs of sone sort of deficiency. It starts about up mid way on the plant and begins with the leaf tip or from the leaf tip and goes inwards on from the leaf tip. Leaf tips or between leaves turn yellow then brown. Its slowly starting to go through out my whole plant. Now my other plant is starting to do it. I was using genral organics go box nutes but i stopped feeding because of possible nute lock out. I watered the shit out of them the last 2 days on my next feed with my other plants im going to fert them as well. I have other plants that are fine its just this one and now the one next to it is starting to show the same signs. The soil ph according to my ph probe is right about 7. I water with garden pure carbon activated water filter connected to water hose. Any ideas or help would be muchly appreciated. Its only two out of my 12. Thanks for all. The pictures are of my worst plant. Please help! Lol.

are you using the calmag?

Seems to be a problem with one of the components of chlorophyll, I'd start with trying a low dose of calmag.

Yes i am using calimagic. I use about half the dosage once a week. Should i up the dosage and fees more times during the week?

it appears you're doing well then, seeing as more than half of your plant looks swell

so the nute chart says to use 5 mls per gallon...is that right? so oyur using 2.5mls per gallon at the moment?

look at the label for the calmag

whats it derived from ?
whats are the % amounts for the N-Ca-Mg

the GH feeding chart suggestions are often times more liable than other brands that suggest huge amounts leading to over fertilizing

I wouldn't be as afraid to use the mix the way the suggest it... for this particular brand,
I wouldn't say that about most of the others!

Wow that's strange...I use the recommended dosage of cal/mag by botan with good results...I can't really tell for certain but is that nibble spots on the leafs that look decent....I also see a lot of your leafs have white tips....If I were you, I'd back off on the N some and slightly increase the Cal/Mag your using....light leafs with green veins are a good indicator of Mag def....but that totally dead area seems suspect IMO....looks almost diseased or pest caused more than a def imvho...leaning toward disease....I'd get rid of that section while your still in veg ....So backing off the N slightly upping the Cal/mag and good watering habits are where I'd start.

I'd also look into some pest prevention as well...it never hurts GL

a few days after you've treated them for pest (maybe 3) id give them 3/4 tsp per gallon Epsom salt spray 1x and then again with 1/4 tsp per gallon a few days later

2 tsp Epsom salt top dress at the base watered in with 8mls calmag per gallon 1x and then back it off to 5mls per gallon thereafter and in a couple weeks maybe go down 5mls every other watering

note; but id like to verify what the calmag is derived from
its from there organic line so im not sure if its the same as the std type most peeps have...
if its derived from gypsum or something organic im not sure itll be available right away... if its just like the other calmags then itll be good and work quicker

I am generally scared of adding anything to soil that is not quickly gone, or from something simple like bone meal etc.

I would move the "sick" plants away from the other, some plants just have peculiar feeding habits, but I am worried it could be a systemic problem.

I have them all in ground so there would be no way to move the sick plant. I just hit them today with some calimagic and bio thrive i havent fed them in about 2 weeks or so. Hopefully she recovers fast. Im thinking it may be a nute def. As it showing signs of nitrogen def. From yellowing of bottom leaves. So ill up the dose on my nutes and hopefully she heals up.
