It’s 18-18-21The way the leaves are clawing down and the darkness of the leaf I would have to guess over fertilizing. What was the npk ratio on the miracle grow?
this is a coco medium, ... quarter dose of MGrow

You're REALLY gonna want to find some way to test your pH, especially if you're not growing organically. Without knowing your water's starting pH, and exactly how your nutrients impact it, any guides you find will be kinda useless. I think you'd almost definitely need to know your actual pH to effectively buffer your medium with lime, but I've never really built soil so I may be wrong. When my last Amazon pH pen had me feeding battery acid to my Gorilla Glue autos, I said "never again!"And no I haven’t had an accurate way to adjust my ph. Don’t have a tester. But I’ve followed some guides on how to use slight amounts of vinegar to lower the ph.
its a coco soil mixWhich MiracleGro fertilizer are you using?
EDIT: I see you said 18-18-21. That's "Tomato." That works with Cannabis. But, maybe not optimal with coco. See next paragraph.
If you're growing in coco (no soil), I think you should be using hydro nutrients. Soil nutrients may not work well. (But, it doesn't look like coco to me. Maybe it's just too wet and I don't recognize it. I've never grown in coco. What was the brand of the coco you used?).
you are correct with everything youve said, shouldi not feed it at all with the pre feed that is in the soil? How should i fix this?You said you gave a quarter dose. What does the product say is a full dose?
I have grown cannabis from seedling to harvest using MiracleGro Tomato (18-18-21). I'm growing one right now, (<<link) in fact. However, I don't have the box anymore. (I put the fertilizer in an airtight plastic storage jar. So, I don't remember what the box said (how much t use). I do know 1/2 to 5/8tsp/gal is about the right amount. I fed as much as 1.2 teaspoon without burn, just N toxicity (which you show some too.).
It's hard for me to believe you've only fed once (quarter strength) and the plant looks that ovefed. I've got a feeling the medium your growing in isn't just coco. Maybe a coco-based potting mix which had nutrients already in it? (The 3rd photo shows a round something on the soil. Is that a time-release nutrient pellet? I was thinking it could be a seed shell. But, it doesn't entirely look like that.).
i will buy a tester and some of that as a backup. Battery acid for these girts doesn't seem good.You're REALLY gonna want to find some way to test your pH, especially if you're not growing organically.

If money's an issue, you may wanna pick up some of this: https://www.amazon.com/General-Hydr...ph+test+drops&qid=1566187836&s=gateway&sr=8-5
That's what I use now. It's accurate, just not very precise. It will keep you in the right neighborhood, though.
