Tiger striping on leaves?

[Oblivi0us]

First two pictures are the leaf problems on two seperate plants
Third picture is just a general overview
Fourth picture is of the baby clone that is getting the same feeding but is happy.


Pictures aren't picking it up as well as being in person. Looks like too much cal mag to me possibly? I think I remember my last grow I was putting less my mix to solve this issue but I can't fully remember.

What are your thoughts? Two of the strains are the slurricane, but only 1 is having these leave issues. My baby small clone cookies dried fruit is taking the same feeding nutrient strength as the bigger ones and showing no issues. Then I have 1 big one that is sherbtang that some of the older big fans leaves are showing this.

My only two guesses are not watering to run off enough causing salt build up and too much cal mag. Or just too much cal mag. I also did just transplant 4 days ago...

I feel like I had this issue before but forgot what I did to fix it. Last grow was 4.5 years ago with exact same nutrients and it thrived, should of kept a journal like I'm doing now.

I know h3ad came back later and said he cut out the cal mag completely.. I think I might of did that too and it helped.. I don't remember ugh!

Thanks for any help

These ml of fertilizer are into how much water?

Is your coco dry or it just looks like that in the photo?

6ml/9ml to 1 gallon of RO water.

I just watered in that picture. Just transplanted clones into the big pots a few days ago, so watering around the root zone to encourage roots to shoot out. Didn't think drenching the entire pot of soil would be good for the transplant

It's not soil. It's coco. Water it and try not to let the coco dry out.

Am I getting it right, you're giving them bloom fertiliser already?

They look like they have a nitrogen deficiency to me.

If my assumption about the bloom ferts is right, I'd change to growth fertiliser with more N in it and probably give them a three-days treatment of epsomsalt showers to get them nice and green instantly (1g of ES per litre)
Spray them 2-3 times a day and you have lovely looking plants by the end of this week.

RO water usually comes with the need for a calmag made for soft water. I know that canna made a version specially for Australia because of it.

I don't think you have a salt build up yet. It's too early in the grow and you barely give any ferts yet.
And if you ever think you run into one, get enzymes into play.They work a treat.

once you have those, by the end of the grow you could even double/triple dose those enzymes and plant your next run straight into the same pot with all the roots left in it. The more runs you do,the better your coco becomes!!!
I reuse mine about 5-6 times before I buy new stuff.

A bit more info wouldn't hurt, but I hope that helps in some way.
Cheers,stiff
