Leave spotting

started grow question 5y ago
Nute burn? Thrips? Some of those leaves where tucked aggressively at one point. I'm leaning towards nute burn. Think I over did it a little.

Same spot on an outdoor plant I have but I know that mine was caused by the temp dropping down to 0 the other night. Fricking middle of june and weather going down to frickin freezing. Global chilling. That will be the new tax grab...

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

Help, what are those weird yellow spots in late veg?
Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

I think it's calmag and lack of nitrogen but any ideas. I've been busy in the garden so have taken my eye off the ball. She looks in great health with praying full leaves but her colour is off. Any ideas would be taken with gratitude.

Bottom leaves yellowing in flowering
My lower leaves started turning yellow and drying out, am I having nutrient deficiencies? My guess would be nitrogen or potassium but not sure, had some nutrient burning earlier so cut down on the feeding a bit.
