I noticed something similar with my plants. I'm in organic soil as well. But it seems to be more of the fact the parameter of the leaves hasn't turned dark green yet rather than it being "discolored" if that makes sense—maybe slightly too much nitrogen. Only my older big fan leaves are that rich dark green and the new ones start to get that dark green color from the center of the fingers of the leaves and work its way out as it gets older eventually the whole leave is that dark green color. as long as you are not burning the leaves it' okay but maybe dial back the fish as it has lots of N ad you are in flower

The leaf discoloration issues is due to potassium lock out caused by an incorrect soil pH.
It is not a magnesium deficiency.
No soil mix on the planet can magically "regulate the pH itself", it is up to you as a grower to monitor and adjust the pH.
Plant is also on the verge of severe nitrogen toxicity.

Living Soil regulates the pH itself, no need to regulate anything. r/o water is perfectly fine.

According to https://www.growdoc.ca/ it appears to be a pH fluctuation...
Can be caused by:
• Root rot
• Room/tent VPD
• Nutrient toxicity (K)
• Nutrient lockout
Use pH reading meter to measure and keep track of your pH.
Use pH adjusters (“pH up” & “pH down”) to help balance out pH before feeding or correcting small fluctuations on daily checkups.

looks like a magnesium deficiency to me, you could try adding some additional rock dust. Basalt can have good amount of magnesium in it, or epsom salts. But could also be excessive Nitrogen, what exactly do you mean with "urb and fish shit every now and then" ?^^

Light colored sugar leavesI'm at the end of week 6 and the plant is looking healthy overall but there are some bud sites that have some sugar leaves that are developing with a lime green color. Im thinking I might have been a little high on the ec so I backed off a couple days ago. Thoughts?

Rate the Bud - 6 Week completed floweringSo this is my first time growing with using BioThrive grow, bloom, calmag bottle ferts. Would greatly appreciate any feedback on improvements, those 2-3 leaves with yellow spots seem concerning.
On 'honest' scale of 1 to 10, how are my buds looking for week 6 in flowering?

Cut off yellow leaves.Can I cut off these leaves?
I am worried that this is an autoflowering plant and it will be an additional stress for it. But it also seems to me that it is spending some effort to keep these leaves alive and it would be better if it spent this effort on the buds.

Sénescence ou manque d'azote en phase de floraison.Les feuilles virent au jaune rapidement, se propageant aux autres. Je les ai privées d'azote pendant 10 jours en floraison, pensant que la terre enrichie suffirait. Doute entre manque d'azote et début de sénescence. Voir mon journal pour plus de détail. Merci beaucoup 🙏

Leafs looks bad. What's the problem?Hi.
I'm a beginner and this is my first grow on coco coir.
2 of my plants having problems.
I'm watering about every 2 days with half amount of nutrients, that the nutrient company is showing on their chart.
So i'm not sure, if it's too much nutrients or not enough nutrients.

What's the problem?Hi guys, basically for the last few days the problem hasn't varied too much but I can't figure out if it's my light or if it's coming from somewhere else. Some of my leaves are curling with stains either on the leaf or like a burn on the tips.
