some type of deficiency?

that REALLY looks like spider mite damage, but if you say its not pests...the closest thing i can think of is calcium deficiency.
but its spider mites...

its within the realm of possibility that that is the beginning of Mag deficiency combined with calcium deficiency....but i'm still leaning toward mites

Thanks for the reply!! But no definitely not mights. sorry I couldn't zoom in closer but the spots start very faint and then progress to a solid brown/rust color.

are you checking ph? have to be over 6.2 to absorb mag. are you in soil or hydro or..? my friend that runs rdwc sometimes has big ph swings when the plants put on a growth spurt, like the stretch

To me that leaf looks full of salts. Too green too puffy. Too much calcium or possibly mag will start to do that to your upper leaves first. You may have built it up from veg.

Should always post plant pic then leaf pic. You tell what is wrong by where the leaf damage is on the plant.

If it were a bottom leaf I would say mag not calcium.

Read. Read. Read. It gets more confusing than this will end up.

By the way. Leech the pots with some fresh water and put back a lower dose of balanced nutes not bloom nutes and wait is all you can do if this is a container grow.

But I am not ruling out mites on those nice dark green leaves. Too much nitrogen brings leaf chewing bugs. They love the soft dark leaves.

try to keep ph at 6.2 however it fluctuates to 6.4, using sunshine mix #4. thats when i started having the problem i switched from ocean forest. same nut program ive always had just different medium.

yeah i know it lookl like some mite damage but ive checked and checked no mites. i have dealt with them before so i know how to spot them. so you think possibly too much cal mag build up from veg and now showing up in early flower? i am gonna flush and do the low dose and see what happens thanks for reply..

You shouldn't need cal mag in veg especially heavy cal mag. That could have a negative effect for sure.
That isn't true. Especially in Coco-based mediums. Calcium, maybe not as much, but Magnesium? You're way off.

However, you are right about too much CalMag. It can cause lockout. What is it? Potassium? Nitrogen? I forget.

It's the safest way to handle it. I don't use the massive amount of water to flush like every guide suggests. I use a gallon of clean water. And a gallon of nute solution to replace what was lost. This is for a 3 gallon pot. i look for the runoff to run clean and check for high EC. And maybe PH but it should self regulate in a proper mix.

Then if it still gets worse you can feed the mag and it will probably be able to uptake again. Be patient.

I'm damn near positive that's an infestation. There's a chance it might be something else, but judging from the lack of rust color in the dispersion pattern, I don't think it has to do with Mg or Ca.

that might be speckle pattern from some kind of spray, it doesn't have the right coloring for Ca. and Ca. is the only thing besides mites that might make that kind of pattern.
i have a 100 times scope and have only ever SEEN mites a couple of times, and unfortunately, i've had them more than a couple of times. i know you say you don't have mites, but i'll bet you a big bud if you spray for them that'll go away
