FYI: you don't need calibration. A sub-gram scale is handy to have. If you can accurately measure 1 gram of ordinary salt (from the kitchen) and mix it into 1 liter distilled water, that's 1000ppm. I use the Horizon Pro-20B scale to measure things like this. It has .001 resolution. But, there are more typical scales that go to 100g with .01 resolution. That should be accurate enough too. (I use the Horizon HB-01 scale for that.). They're both cheap scales, you find them on ebay.

I noticed more of the leaves are starting to get a curve to them.

Curving sideways like that last photo? (<<link) @Dirtbag sees k-def. Maybe that's related. I still think it's underfed, not overfed. Kdef can occur from too little (or too much) nutrient. It's been a few days since you flushed. It might be a safe bet to feed 1/2 strength the next time you water. (I don't recall what you're using. If you have MiracleGro "Tomato," that would be 1/4tsp/gal). If it immediately improves, then it's hungry. If nothing happens, or it gets worse then everyone was right and it's overfed? Or something else.).

I was thinking. If you did the dolomite (raked it into the top 1/2", poured it in, whatever) that could have released calcium which can interfere with K availability. I think that would mean there's not enough K in the soil. The flush could have caused that. Or, it was underfed to the begin with and didn't need a flush, which would make the Ca to K imbalance worse than flushing excess K (and other things).

I didnt add the dolomite yet. The only thing I did so far was flush it.

I can't read those color-match ph tests. It looks relatively neutral to me. What do you see?

If you flushed and it's not improving, and the ph seems ok to you, I would lightly feed next time. If the ph doesn't look good to you, maybe the dolomite is the thing to do. Deficiency could be due to the soil ph being off. But, it doesn't loo that far off to my eyes..

It didnt look far off to me also. I have a 10gal pot i was going to repot it in before it starts to go into flower would that be a good thing to do?

I don't know. Sometimes doing too many things makes it hard to figure out what's wrong. But, maybe new soil would feed the plant.

If it were me, I'd probably leave it alone and feed it.

What soil would you use?

Overthinking it? confused? LOL don't worry it gets easier (remember the kiss principle) add a tablespoon of dolomite per gallon to the new Fox Farm as directed when you transplant and then start correctly pHing what you feed with a meter to 6.5 and your problem should straighten out quickly, though the affected leaves won't likely come back. Don't overthink it, it's not that complicated, if I can help again just ask, good luck!

Kinda like this?

You can find out what causes that at this link my friend, good luck! https://www.thcfarmer.com/beachwalker/

Ps. If you'd like I can tell you what I did to stop that condition, and show you the plant afterwards too, she's looking good! Feel free to ask questions in that thread if you would like, it's my grow journal featuring Romberry

Romberry by Freedom of Seeds

This is a grow I've been threatening to do for several years now lol ;) It should be fun, hope you enjoy the shenanigans!? This is Romberry, perhaps the easiest cloning plant I've ever had, she wants to grow big and bushy but she can be trained. She's a...

If your Ph is 7, you don't want to add any lime to the mix. It looks like a possible Magnesium issue, as it can cause chlorosis and necrosis, and Magnesium doesn't get well absorbed in alkaline soils. 7 isn't alkaline, but it is close to the cut off range that makes magnesium available. I grow in Promix, which is similar to your mix , and I've never seen anything like it. Since everyone is throwing darts and hoping to fix the problem (myself included), one solution might be to treat a branch with a light foliar feeding, including some cal-mag. This will bypass the roots and any benefits should show up fairly quickly. By treating just a single branch, you won't make it worse for the whole plant if the case is overfeeding, and if underfed, an improvement will show quickly.

Sorry about the first link. Here's that plant with the similar issue to yours today, she's 54 in. tall and has at least 18 tops couldn't take her out for a better picture cuz she's wired to the tent pole



The grow Journal is slow because if I'm honest the plants doing exceptional so I post an update & a pic once a week and there's little more to say but it's not a usual grow I'm using jobe's plant spikes

however I have everything I've ever fed or done to every plant written down, if you want to stop by with any questions I will try to answer and I will go find the documentation I have on this plant too if you'd like, although I think I recall what started this issue but I write everything down old school style so it takes a minute to find LOL good luck

Btw you don't want to do a nutrient spike grow, believe me it's not fun! It's not difficult, it's more annoying than anything else & you'll likely hate it, I do already :/
