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 :)

Looks like a lockout or pH issue. Plant is struggling to make 5 fingers on its leaves. Start with a slurry test and report back

Those two with the 3 leaves are a clone from a friend I got 7 days ago. It just started making 5 leaves.
The big one was a clone acquired 4 days ago.

The small one is the only one I rooted myself from a fresh cutting.

The 6ml/9ml is gratefulh3ads modified version of the Lucas formula. This is the suggested feeding.

Following labeling instructions is never a good idea. Cut all that in half, you'll probably never need more than ⅔ strength

I am NOT following the label on the nutrients. I am following H3ads coco formula. If you google it you will see it's been around for 10 years. I will check out doing a slurry test, thank you.

Blue lab, Apera, and Hanna make these soil probes. I’ve been told by wiser men than me thatve used all these brands that while it’s still not perfect the Apera is the best choice. This information is also almost 2 years old so there could be better options from different brands by now or possible that the brands I’ve mentioned have come out w newer models.
Nonetheless, it took me a long time to find out about the pens when I was having my own war on potential hydrogen.
Hope this helps fellasbongsmilie
