Burnt edges / yellowing
What are all these burnt edges from? One of the burnt leaves is from the perimeter, so I'm not sure how it could be receiving enough light to burn. I also have a small amount of yellowing towards the bottom. That's normal during flowering if the low-light leaves die, right? Thx

Yellowish spots ? Magnesium Deficiency ?
I noticed that on some leaves (not the new ones) there were 2-3 yellowish spots. And on a large leave, a point that turns brown. I thought about a small deficiency in Magnesium?

Yellowing, curling tips?
I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake

K deficiency? Hard to believe that can happen in 65-gallon pots.Are getting big though.New growth tips looked yellow,hit them with water-soluble K and the new growth edges seemed get green.Some toco-ing, humidity is kinda high. Too intense light(800 ppfd), not enough C02 maybe?

Bottom leaf turned yellow with brown on edge
Hello this is my first grow and had noticed a leaf turned yellow with brown spot on the edge. This is a northern light auto just kicking off with her flowering. I use advanced nutrients 3 in 1 micro grow and bloom and that's all I've ever used. I suspect a nitrogen deficiency...?

Anyone know what's wrong with my girl?
Can anyone tell me if this is going to effect my flowers? Should I cut these leaves out? What can I do to correct it? I left a pretty good description in week 7 of the battle with this plant.

Slight leaf tip "burn"
What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 1000

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10
This is my second attempt at cocus I work with Plagron nutrient solutions(Coco Nutrient) I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!
