Looks like a combination of hot soil and magnesium deficiency 🤷♂️🏻

Does anyone knows if should I flush the pot ahead of time to reduce nutrients levels?
As you can see from last pic from week 6, I have used pre amended soil with 2.5 % of Nitrogen on dry mass. (sorry for the italian). Should I flush the pot ahead of time in order to reduce nutrients level so to both solve the yellow tips problem and favour the flowering stage?

I see that there are yellow leaves with brown spots, the tips of some leaves are "burnt", and I also could see very small flies I think they were "Fungus Gnats" and that they may be the cause of his yellow spots, am I right? and how many weeks would you wait for the harvest? thx!

Leaves turning brown/purple
The leaves on one plant started to turn a little pale, and with brown/purple spots. And on the other plant it starts to turn more yellow, probably Nitrogen deficiency for this one. What do you guys think ?

Rust-colored margins and dots. Potassium excess, Calcium excess, or something else?
I need your advice to get back to feeding. I kindly ask you to read my last comment (27/07) in the diary and take a look at the whole diary. I also uploaded a video. Thank you 🙏

What am I facing? Plant is getting worst everyday, and I can't find the reason why. Thought it was a calmag def, but now I don't really now.
When I switched to flower, I started watching some rusty spots on the leaves of the gelato. After doing some research, I thought I was facing a calmag deficiency, and starting adding some calmag. Plant is getting worst, I flushed the roots and water between 5.8 and 6 as canna ask

Should I harvest early? Light stress, leaves browned and dried out, buds are all amber pistils
So this plant has been suffering from light stress for the past two weeks or so. I have removed all the dry and brown leaves. The buds still seem fine-ish. Should I just give her the chop early and save what I can? She's been flowering for some 6 weeks.

Esto es normal? Floración - Double cookies auto
I'm in my last week of flowering, and recently the leaves started turning like this very quickly. Is this normal? Did I do something wrong? I have 4 autoflowering plants that are in the same state. A lot of yellow leaves have been falling lately, but the buds aren't maturing.

I have been having trouble with my leaf tips and edges appearing yellow and then turning brown. At first it was just the bottom leaves that were affected but now more of the top leaves have the burnt appearance just not as extreme as the lower leaves. What can I do to fix this?

Brownish stains after transplanting
What do you think this is? I have recently transplanted it outdoors. These stains appeared the day after. Might it be sunburn? What can I do if that’s the case?

Is my plant giving a warning
I'm not sure if I have a problem or it's normal. Some tips show damage I think it was the light to close so I moved it back over 12 inches away. I am giving the bloom every other day but half of the water i give. No nitrogen is being given,hardly any ever she doesn't like it.

problems with low leaves
in the lower part of the plant some leaves are yellowing, others are drying out and even detaching. can it be due to the fact that since flushing (a week ago) I have not given anything to the plant anymore? I hope this does not compromise flowering
