I've noticed a few brown spots on the main cola's leaves. The rest of the leaves are looking normal. What could cause that?

Calcium deficiency use calcium magnesium. Could be boron but that usually has twisted leaves and starts at the tips and is rare

Bud rot? Mold?My plant is a bit problematic ("quick one" Auto from RQS, outdoor balcony grow).
I'm a bit worried that I have to throw it out, therefore I would like to ask for your expert opinion. :)
1. Is the "brown stuff" on the top bud "bud-rot"?
2. Are the "more intense white spots" mold?

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.

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.

Foglie bruciate.Hey guys! Hope everything's going well. I have some burns on the leaves of just one plant, I gave it bio grow and top max biobizz. Humidity is at 50% and temperature is 27/30 °C unfortunately. I think it might be due to the lights being too close, but I wanted your opinion. Thanks a lot!
