How old is she? First things I'd check are the soil and then the nutrients. The soil looks like it could do with better aeration but to me she looks hungry.

Is this a deficiency?
Hello there, Today I saw that some of my plants have some curled and sad looking leaves (see pic). The soil is pre-fertilized and I currently use normal tap water (p.H. adjusted) for watering. My plants get 18hrs of light a day (approx. 300-400PPFD) Thanks for you help guys :)

So I use 5 ML per gallon of fox farm Grow Big Liquid Plant Food, And 5 ML Per Gallon Of Fox Farm Buds And Blooms Fertilizer. I'm barely staring to Introduce Cal-Mag so I don't think the Cal-Mag is causing the issue, I water every 2-3 Days. Temp is Right Around 80 during the day 7

What deficiency this is ?
Perhaps in these pictures you can see better, what deficiency this is, whether it is phosphorus, potassium, magnesium or zinc?.

Yellow Borders and Curling inwards slightly?
Some of the new leaves on 3 plants have got slight yellow borders and are curling inward slightly (please see third pic in this week) - is this due to over watering, nutes? or something to do with humidity? Many thanks!

My Royal Creamatic has the edges of their leaves pointed down, loosing soil and some yellowing in the older leaves. I've tried to use google but there were many opinions about this. Have the feeling that I should just give ph water for now. Any ideias/advice? Thanks

Leave colors on 3 week old clones blackberry Kush in Coco coir and a jiffy disk
Sudden yellowing and discoloration of a e or 4 week cutting. I water it when I see the Coco getting a little dry. I make sure there is at least 20% of run off water. I watered with pH corrected water to pH of 6. I also add a small amount of canna bioryzotonic for their roots.

Burnt, should I throw it and start from zero?
I have 1 burn auto for excessive light, should I throw this one and start from seed again or maybe flipping to 12/12? The light is farther now but maybe I can do something else than put away my lights.. my current schedule is 18/6 and the plant is around 45-50 days old

Yellowing dry leaves, late flower.
About 2 weeks from harvest time, the yellowing leaves which I put down to an early fade have become dry, brittle, curly and splotchy. Should I worry this late? Is it potassium defeciency, lockout? Should I begin flush? Add molasses?

Early growth sick plants - photoperiod
Purpling stem, yellowing leaves, droopy leaves - I’m thinking nitrogen deficiency, but I’m not sure if I should add more nutrients or not to my current solution or if I should flush completely. PPM is at 850, and the PH is 6.3. What are your thoughts? Any GH nutrient schedules?
