I can’t seem to identify this issue I think it’s a calcium deficiency or a phosphorus one?

An excess in N can produce a less uptake of calcium I think you have a little N excess so give less N add some calmag and see how is going.
You can check the PH of the drainage to know if you've an acid medium wich slows the Ca and Mg uptake.
have a nice day friend.

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.

Browning, curling of Green Crack leavesIs this discoloration worrisome? Ph 6.1, adding 1tsp calmag to each gal, EC at 1.5. What's causing this browning? Seeing only on the Green Crack, mostly higher leaves, but some lower too. Does it need more or less of something? Leaves look "dirty".

Please say it ain't bud mold :(Noticed a brown spot on my center cola last night. This morning it progressed so I removed it. I'm noticing browning on nearby leaves. It may be nute burn (I have been heavy on them), and I did recently increase light intensity to full two days ago, but my temps are ~74f. Pls no!

Pest attack. What can I use to eradicate?3 weeks of flowering, and the pests are still here. Can I play Beauveria Bassiana? Or just neem oil?
- The temperatures were very high here, exceeding 30°C, this week it will decrease.
- I have other plants to harvest and I'm going to take advantage and clean the grow.
