Nutrient & critter problems need 1-2weeks from harvest need advice
The plant is a couple weeks of harvest but has some issues. (Some kind of nutrient lockout or deficiency can't tell what tho, pH is fine at about 5.8) And I got these annoying critters that seem to live on the soil (but aren't touching the plant) Any ideas on what to do ? :/

Yellowing leaves on autoflower dwarf
I'm 12 weeks of vegetative growth deep with an auto-flowering dwarf strain. My plant is nearly 1.5m tall, showing no sign of flowering but I'm starting to get a number of yellow leaves lower down the plant. What is causing this? Should I leave or remove them?

Yellowing leaves and nutrient lockout. How do I fix this? This has been a long time problem. Definitely overfed for the first 3 weeks of flower.
Lemon Cherry Cookies locked out for weeks. She's yellowed up big time. Took in less than a quarter gallon water yesterday and a half gallon today. But then she had a higher EC and TDS before adding plain pHed water both days. After topping off it went back down. Check my diary.

What could happen? Low temperatures? Over-fertilization? Or lack of nutrients? Please help, it's the only leaf on the whole plant that looks like this.

Yellowing leaves on bottom and middle
I am growing in organic soil and transplanted 3.5 weeks ago from .75 gallon pot to 2.5 gallon pot. I noticed some yellowing on some of the leaves, generally towards the bottom but a little in the middle. Is this a cause for concern or do some leaves natural die off?

Is this light burn?
Is this light burn? If not what is it? It's under a Phillips 13w household led 2700k bulb, it's not the only affected area but it's the most affected and the closest to the bulb. I plan to add more but don't want the issue to accelerate. Thanks in advance!

Lower Leaves Yellowing
I have noticed that a lot of lower leaves are turning yellow. Theres nothing special going on, it just fades from green to yellow evenly. I am feeding it Veg nutrients 3:1:3. So it can't really be a Nitrogen deficiency right?!

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?

Nutrient lockout? [first grow]
My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before. Is it nutrient lockout? Or just deficient? Appreciate every feedback!
