Cold temperatures then ,something is causing it. 15.8 way too low, at 15 cut off zone of activity for weed, raise a bit. It lock outs calcium too ...
It could be damn sensitive genetics as well ...

Temperature never passed 25.5c and at lights out it goes down to even 15.8c, slight breeze really not to much just leaves looks like they are vibrating so i guess i have good circulation too

When they get cold issue, they look droopy generally, yours like praying, so I would check temps at top canopy level. Don't go further than 27 cel. Target 25.

I gave my guess based on your words and believing that hat you do everything good with food and pH, then only too close light, or too low temps can mix calcium

Lights too close and intense can cause it too. Looks like deficiency, but in reality burn out and incapability to photosynthesis because of calcium issues cause this.
All the Best !

Rusty Leaves3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera.
I also have slight "clawing" on many of the upper leaves.
Mg/Ca lockout because of nitrogen toxicity possible?
Doesn´t seem to be fungi, as there are no spores to rub off.

More rusty spotsSee this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing.
Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.5y ago

Deficiency or ending cycle?Hey!
I was hoping someone could tell me if the first plant has a deficiency you would recommend I correct or if she is slowly coming to an end of her life cycle and I should just let her fade?
The last picture is my other plant, less severe, but same question :)
Thanks!

Last water yesterday.Plants are suffering from an early stage of calcium deficiency, received a bottle of cal-mag today. Watered last night cause I didn't want to wait any longer.

Problema con mi Runtz MuffinBuenos días,
Tengo un problema con mis hojas, (puse fotos para que podáis ver).
He visto que podía ser un deficiente de fósforo. Pero también puede ser un problema de calcio y de magnesio.
Alguno podría ayudarme con eso ? Que tengo que hacer ? Añadirle un PK 13-14 ?
