Can someone help me out. Trying to figure out what is happening with this plant. This is my second grow didn’t have this problem with my first grow. Thanks
Couple of questions: what soil are you using and do you know your runoff pH and PPM? What product(s) are you feeding?

I’m using roots organic soil and bio bizz nutrients.

I was told no need to test runoff with it being all organic.
It’s my understanding as well. Let’s wait for an organic grower to see the thread and step in to help.
Organic grower here.
You normally don’t need to check PH or PPM unless you run into a problem that may be due to the soils PH being out of range.
This may be one of them. It’s always good to have those skills in the toolbox for when things come up.
I’m not familiar with the bio biz nutrient line.
Are you using tap water or RO water etc.
You want to know the PH if using Tap water
Tap water if hard water can add calcium and raise PH up.
It’s looks to me like a potassium deficiency either caused by improper PH of soil (6.2-6.8) is the range you want.
Could be due to not letting it dry out enough between waterings.
Could be due to not enough nutrients available to the plant.
Hard to say without sharing more details of your grow.
It looks like an Auto in maybe a 3 gallon pot?
Temps day night
Humidity day night
Lights used and distance
Watering practices
How old from seed
How long into flower
A flush may be needed to help just don’t know for sure

Less experienced grower here so you can take my opinions with a good grain of salt.
I’ve grown in fox farm soils only, and as I was also told that runoff is not a necessity. BUT when the plant is showing some type of excess/deficiency it’s always nice to have some runoff so you can get a reading on what the plant is uptaking or not.
I personally don’t water till runoff until flowering stage. Then the waterings that are only water and no nutes I will water until runoff to get rid of excess salts and also to see what is still in the soil from the previous feeding.
My opinion is the next time you water, water till runoff so we can see what the plant needs or doesn’t. Looks to me like a nutrient deficiency/ excess or PH issue.
I’d recommend watching build a soil 10 x 10 they talk about a lot of good organic information. Also they tell you don’t chase your tail. Which to me seems you’re starting that process.
Non-experienced grower here.
I believe it’s 100% necessary. My runoff numbers tell me how much to feed next time. How much they ate last time. What my pH level is. You know all those not important things
Perfectly good and beautiful plant flushed yesterday.
FFOF/HF and Seedling Warrior soil mix.
Numbers changed with 5 gallons of flush (6.5/500PPM).
Started high, 2800PPM
Last run-off, 6.2/1531 PPM.
I quit on that plant.
Got a couple requiring diagnosis and recovering.
Knowing how to feed is important.
Knowing how she eats is the goal.

Plant looks good there’s definitely some dark green in them leaves possibly cut back a little bit on the nitrogen. I only grow Auto flowers I never feed them over
1100 EC total. My runoff I want to see between 1000 and 1200 EC I know that doesn’t sound like a lot of nutrients to feed but autoflowers doesn’t require a lot. I’ve never fed over 1100 EC and each plant gets between 5 and 11 oz
It gets easier and easier as you go

Believed origin is White Widow and my strain is always dark green leaves.
Easy slow cloner, from 3/22 purchased clone origin.
Harvested and cloned during least 3 grow periods.
Seeds mixed somewhere with something.
Never again outdoors to indoors.
Don’t need bag seeds, anymore.
My 8/23 clone mother, sits outdoors, again, awaiting summer, if she survives.
Thanks for sharing.

The difference is what your feeding them as to watering to run off and salts built up or not.
True organic amendments don’t have the rapid salts build up like the chemical chelated nutrients.
If your grow style is chemical then you will need to continually monitor those things as your nutrients choices dictate those things.
Living soils and organic nutrients do not require constant baby sitting and measuring PH and PPM unless you run into an issue has been my experience anyway.
The microherd in the soil do their dance.
Your 2800 ppm run of number and subsequent drop to 1531 was happening because you were washing away the nutrients that were in the soil and now it’s down the drain.
The pic of the plant a couple post up look good to me

Not saying it is not related to nutrients or soil pH, but my go to when I see the tips of the serrated edges on fan leaves a lighter green or burnt looking is overwatering or too humid.
Here is an image from Growweedeasy in an article about overwatering and the 5 most common signs

Used run-off to wash sickly plants.
Usually avoid flushing, for that reason, exactly.
Wanted to flush a good plant for number recording, then hit the sicklies.
Got a couple that need repair-recovery.
Contributed narrative and numbers in support of original discussion.

Interesting, extremeties like hands and feet numb, tips and margins too.
