With magnesium you would have browning on verge of leaf, here rusty spots all around leaf, so i would say its calcium.
What caused it could be a lot of reasons.

But be careful with the calmag it’s very potent, don’t feed to much. Start with the half dose they recommend.

Calcium deficiency is the rusty dots so to prevent them coming give her calcium. Might give her little magnesium as well wouldn’t hurt in this case. So would recommend adding CalMag to your feeding, and your leaves looks a little light green so might give her some more NPK/a+b as well to boost the growth.
Good luck my friend and may the buds be with you 😁🤩

Gray leaves on buds with a massive concentration of trichomes. What is it?No clue what this is. Light gray leaves, tons of trichomes. I'm a bit confused here. Should I just cut the buds that look like this to be safe? Or is this normal?

Black spots spreading // Need your help!Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...

At what stage do leaves get darker ? This is confusingI overwatered them at the beginning of veg and then I fed them with 0.7 ec nutes max, EC would go up if I gave more. I've had tips burning probably from light too close. I find that leaves are pretty dark but it may be because of the strains. When leaves do get darker in flo ?

The problem in plants when I supplying CO2Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?
