Looks like rust, deficiency or excess?

[Jungle Joseph]

One of my plants has what looks like rust on the leaves. And the leaves are crispy.
Growing medium is coco perlite.
I'm feeding 3 times a day to runoff with EC 1.5 and pH 5.8
Temp, 25deg c
Humidity, between 40 and 50%

Nutrients are as follows,
5ltrs water, pH 6, EC 0.0
2.5ml fulvic acid
12.5ml coco a&b
12.5ml crystalic
15ml bud burst
15ml flavor savior
5ml calmag

That brings it to pH 6.5, I add 3ml pH down to get it to pH 5.8, EC 1.6,

I haven't moved the light.

It started at the top of the plant and has been progressing down the plant over the last few days.

Hey @Jungle Joseph great lady.
Hope you are well my friend.
Are you putting the calmag into your mix first?
Always goes in first to help with nutrient uptake.
Your a little light on calmag also I'd go up to 7-8 ml.
Try cutting back on the A and bump your ppm on everything else.
Try and get your ec closer to 2.
Stay safe.

Hi JJ - looking promising
First off - clusters of white spots, assume no bugs?
Calcium def maybe caused by whatever is in all those additives - do you know what's in them?
Nearly 15ml/L of additives seems quite a lot to me
Flowering ok though so I wouldn't worry too much brother

Hi growings,
Spots are orange, not white, could be the camera. No bugs visible with loupe.
Nutrients are from nutrifield.
Pics of nutes,

Im with @Bill284 - add that calmag to the water first, stir well, let set for 15 mins then add your other nutes.

More pics of nutes, sorry about my camera skills.

Thanks Bill,
I didn't realize the order of adding nutrients was a thing that matters. Will be adding calmag first from now on. My EC was closer to 2.0, I've just started lowering it in accordance with the manufacturer feeding regimen. I'll go back to EC 2.0 then.

I didnt know it either - then my friends here set me up for success!

Thanks, I appreciate everyone's help.

Nutes all look good, but in the first pic, bottom right, there is def something going on with that leaf along the veins and the leaf margins on some leaves? That surely can't be any kind of general nute thing?
I recently saw some rust spots on one of my plants that was a K def, but they weren't pin pricks like that, they were more like bulls eyes (remember those pics, Bill?)

More pics of the leaves. The problem ones are closer to the top of the plant.

Some closeup pics.

The droopy bloated fan leaves just look a lot like over-watering, creating humidity down there
The necrosis is appearing at the end of affected (specked) veins, right?
Mites prefer hot dry air towards the top of the plant and will migrate upwards to avoid humid conditions
As far as I'm aware there are no other issues that cause that kind of spotting
The slight discolouration of sugar leaf tips could be entirely normal
Just my farthing's worth

Is it a fungus?

Is it a fungus?

It's too localized for anything like that I would have thought
ps Hello Krissi

Calcium def shows as spotting on upper leaves first with a curling or twisting of lower leaves.
You can mix a 15% solution of calmag in water and spray the leaves right away.
Will kick off the improvement of them.
Stay safe.

Hey Grow how goes it bud!! I was just hoping it wasn't the start of something else...I know little about specific funguses or anythingwell more like nothing lol I probably wouldn't be a big help anyway

Really?!? I didn’t know that! Good thing to keep in the list of tips and tricks!

Yesterday I made a mix of 2ml calmag per liter and foliar sprayed her with it. I also adjusted the plants into a better position under the light. I tied some branches to hold them up, especially with the offending girl leaning over because of the extra weight of the spray on her. While I had her out I checked everywhere for mites. No sign of anything at all. I left her to soak up the calmag in a shady, breezy area. Once she was dry she went back in the tent.

Today I changed my nutrients, and my mix routine.

Started with 5ltrs water, pH 6, EC 0.0
Added in order,
8ml calmag, stirred and waited 10 minutes.
2ml fulvic acid
Coco a&b 10ml
Crystalic 12.5ml
Bud burst 20ml
pH down 6ml

Came to pH 5.9
EC 2.0

Tent temp 24deg c
Tent humidity 41%

Hopefully that helps.
