Both Magnesium and Calcium deficiencies can create rust spots. Give the link I posted for you a quick read, it may help.
First time grower here, need some advice
- Thread starter Mr pig
- Start date
Just had a read now and thanks, I have been resorting to try and find it online from its description lol,
so too much nutrients can be the cause, as can the ph of the soil being out, im giving them some water in the morning so I will check the ph and see if its that first I think
Also @Jeffislovinlife
Hi doug , I feel like it looks like this... its very close if not identical as I've had leafs dry up like that and drop off, I mentioned earlier too about it ,maybe a day or 2 ago
Also got the tips gone brown and curled upwards on some leafs, and on another it is more rusty, pictures are below to compare both plants

It is possible but it does not seem to fit all the symptoms.
I could do with your thoughts on it, im getting confused with all the similarities tbh

Here's the reason why we can't give you a straight answer. You need to diagnose it and cancel out possible situations that only you know.
There are to many possibilities for us to nail it down for you if that makes sense.
Become a detective and begin canceling shit out.

I am with @Wizzlebiz on this. There are a few things that could cause this and it is useless to tackle all of them at once or you will never know which it was. You said you just started Calmag so if it were me I would remove the few damaged leaves, keep feeding Calmag for a few days and see if it keeps developing. If it doesn't you got your answer. Either way it isn't going to drop dead over night so you have some time.
Yes I have been doing that, I gave calmag it was 2 feeds ago as I thought it was a defficiency that way, not full amount but a little
Then I gave nutes the feed after, 800ppm, and today I noticed this,
My next step was going to use water only and test the ph coming out
And then using a pk at reduced amount feed after if its not ph problem
I have 2 I can chose from pictures below
This was to rule out potassium I hope, and not to lock out nutrients at this stage in flower

Your in soil if I remember correctly. The runoff pH won't help you with soil. Its about what goes in that counts.
It seems to me you options left are flush and start over nutes wise or just continue nutes and see if it settles.
How fast is it spreading? Does it rub off onto your finger when when you rub a leaf?
No it doesn't rub off, I checked that at first, and seen somewhere that if it rubbed off, then its a fungal infection or similar
It has just appeared today, u had a slight bit on one that wasn't moving , just stayed the same, and then today on lower leafs near that bud came the newer ones,
Also turned up on another plant too, checked it and it doesnt rubbed off either,
I only watered them with nutes yesterday
It seems to be spreading on this plant quite fast, just 3 leafs on the top bud basically

What you want to see is no new leaves developing it. The damaged ones don't really recover from damage, just stop getting worse.
OK, I will keep a close watch on them as usual I guess and see how it works out
Just in two minds about adding calmag or just water though and then do calmag after lol decisions decisions
OK, as I gave them calmag and from what I've read calcium is less likely but magnesium is more likely whilst in flower, im going to give the some of this organic magnesium I got, 1 scoop per 10litre,
It does show to give magnesium in flower on the nutes chart I use as a base line

Hi guys, hope you are all well.
So coming to the end now with this grow, just about into week 12 and still waiting on the trichomes going milky, got a few amber ones but not many,
So can you guys explain to me how it happens at the end
Does your pistils retreat and some turn orange , then your trichomes start changing?
Just curious as to what you guys experience when growing. I still have a small amount.of pistils to go yet, but I've never smoked any with those sticking out before so I'm guessing its not ready lol

Just coming into week 12 on Monday in regards to age of the plants

All pistils browned and receeded into the buds before any amber shows on buds themselves for my plants.
Generally takes a couple weeks after pistils are done.
Il have amber on the sugar leaves but not on the bud it self during the pistil receeding process.

All ladies are different and if you are like me always waiting on them you are making it the hardest thing to do in growing is waiting for your ladies you wait for them to pop and then we train them and then we wait for the flowers to start and when they do they teach us the biggest thing of all patience as always thank you for your time and the opportunity to learn more about growing
Thanks for the reply, I have some lower buds that really aren't as far on as the higher parts, most likely they will not be so good, I think next time I will chop off the little stuff.
So if your looking for a good signal of when to stop feeding nutrients, you could wait till the pistils show signs of going orange and retracting and then stop nutrients..
