Having problems please help

Hi I have a og kush plant here showing some problems that I haven't had before, I'm using canna A&B with canna coco pro and perlite, my ph has been 5.8 to 6.4 and my temp has been 24c to 27.

I transplanted a week ago because I had purple stems and was told to, also I am using a little bit less of the a&b only using 6ml per 3lt of water.

Are you using CalMag with your water?

No I'm not I have been told of a few people from my neighborhood that there's enough in our tap water.

That looks like the same problem that I get when I don't supplement my tap water with Cal Mag. I will notice yellowing between the veins of the leaf.

You can read up on it here and decide for yourself.

Hopefully an expert jumps in to help., Good luck!

That looks like cal mag deficiency. I'm dealing with the same issue. Try adjust your ph between 5.8 to 6.2 as well

Well I am on 6.2 at the moment I'll keep her in that range, say if I keep her in that range will I still have to put cal mag in.

Yes, I would add CalMag with those symptoms. I don't grow in coco, but I believe that growing in coco requires more CalMag than growing in soil.

I think you may have gotten some nutes on that one leaf ,is it more than one leaf.

I also think you need cal mag, and is your pH down a phosphate based. Phosphate based down effects cal in a bad way.

Don't think Iv ever got my nuits on my plant, it has kinda dryed out that is why I dident know if it was a cal mag issue, or something elce also they are 2 diffrent leaves on them pictures, and that first picture with the drying leaf has only happened on one of my leaves but I am getting some yellow spots as well.
As for my ph down I will upload a pick of what I'm using

Also my ppm of tap water is 490ppm I thaught that would of ment there was quite a lot of calmag in the water I'm using, but just like people told me she might need more than the other.
