Couldn't find any info on this. Plant seems otherwise healthy but growing slow.
Any ideas?

Can ya tell us how old, what medium, what nutes, temp, PH, etc.?

Its kinda hard to tell from the pic honestly by how bright it looks i wanna say its nute burn and if its cal mag deficiency which is usually the culprit with the rust then just give it some cal mag.

seedlings poked outta soil on Dec 27th so one month and a day. The soil is good compost from my gramma
heheI've transplanted once into planters probably 3 gallon, and added a bit of blood meal and lime dolomite to the soil during transplant.
Temps are around 80 daytime and Humidity I'm struggling to raise above 20 percent.
PH im unsure of. Cant find a soil ph meter in my area for a couple months.
And BSD i did see that actually, but It's rare isnt it?

Where can i find this? Garden Centres are far. But i do have epsom salts, i know that would help the mag, is there any way i can get cal from something else?
Rare, but it's what you have. The low RH confirms it too. The plant cannot uptake potassium/nitrogen so it cannot uptake boron as wellseedlings poked outta soil on Dec 27th so one month and a day. The soil is good compost from my gramma

It's often mistaken as a calcium deficiency as it looks the same but is not the case. Which, you say you have dolomite lime in the soil so there is no reason to ADD calcium as dolomite lime contains calcium AND magnesium thats released at a slow rate over time. The dolomite lime also helps prevent the soils PH from dropping as well as it's a soil buffer."Boron is not absorbed well by cannabis without enough potassium and nitrogen, or if there isn't enough moisture (for example if plant is underwatered or humidity is too low). That's why it is recommended you water your plant with a regular dose of nutrients below.A plant is more likely to show signs of boron deficiency when the humidity is very low (below 25% relative humidity in the air), so you may help humidifier may be needed if your grow room is very dry.
Please note: Boron deficiencies are more likely to happen when a grower is using heavily filtered or reverse osmisis (RO) water to feed plants, since boron is found in most tap water."
Nute burn is browning at the tips of the leafs. I do not see this at all. Also, you can see at the bottom of the plant there is yellowing leafs, which means the plant isn't getting enough nitrogen. And no. rusty coloring is much MORE then cal/mag deficiencies. Please research deficiencies a bit to see what I am talking about. Rusting leafs ALSO can be caused by PH fluctuations.
No, don't say ALWAYS. That is NOT the case at all. Research on deficiencies a bit to see what I mean.
And saying "get some cal/mag" WON'T solve the answer all the time. Most likely, cal/mag won't solve shit most the time. Just causes more problems.

I didnt know this about the time release of calcium and magnesium from lime dolomite, but it shouldnt be a nitrogen problem... its got blood meal and healthy compost.Rare, but it's what you have. The low RH confirms it too. The plant cannot uptake potassium/nitrogen so it cannot uptake boron as well

Yeah i tend to believe its the humidity too... No money for a humidifier at the moment but i can wet towels , leave bowls around etc.
Yes leave moist items nearby the plant. Also a bucket of water will help raise the humidity. Is it in a box or closet of some sore?

Around here it is currently 15-20% humidity. I don't have the problem. Also ph is 7.0-7.1. Still no problem. I'm thinking that compost is the culprit.

Yes, a cabinet roughly 2 ft by 2.5 ft

You can order Calcium Carbonate from amazon for relatively cheap if you can't find it at stores near you. It might be a little bit more expensive but for cheap things like that (<$10) sometimes it's worth it to avoid the hassle of trying to find it.
You can still run into cal-mag deficiencies with dolomite lime in the soil. For one it is very slow release, as you said, but moreover if the pH of your water is acidic then you can deplete the DL in the soil rather fast due to it buffering the pH as you said.Rare, but it's what you have. The low RH confirms it too. The plant cannot uptake potassium/nitrogen so it cannot uptake boron as well

Remember some of the best weed on earth grows in some of the driest climates. Once it flowers it will produce extra resin glands to protect itself from moisture loss and you will probably wind up with more potent weed. I wouldn't worry too much about low RH, if everything else is in line it shouldn't be a huge problem

Same goes for outdoors i can assume!

It's obvious his issue is a pH problem. Unless your water pH happens to perfect for the mix with fertilizer (which is incredibly rare), it will cause these exact type of issues. 98% of growers I know can't grow a healthy 3 month crop without a tester to adjust their pH..........
