The leaves started curling upwards, turned brown about 2mm at the top and a lot of small brown spots appeared on the leaves.
I don't understand why or how...
Im using BioBizz nutrients, little less than recommended.

That is Nutrient Burn. All things considered, it's incredibly common.
Especially because most fertilizers are too strong and even their "recommended" dosage you should cut in half.
That is either too much (P) Phosphorus, or excess (K) Potassium

leaves dry and curling upGelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches

1. Over Fed (seaweed?)
2. Burnt? Cauliflower..
3. Calcium Deficiency
4. Hydrogen peroxide 12% Food-grade 30/70 Mix.
Personally I think it's the hydrogen peroxide 12% mix, the hydrogen gave one of its atoms to the neuron of the Diatomaceous earth metal clay. With help from heat

Leaf damage/discolourationThe yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

Brown rust spots on oldest leavesBrown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?

First time growing/Need help in late flowerOver the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?

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.6y ago

Brown yellow leaves?Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.
