Yellow leaves

Recently I’ve been noticing some yellowing leaves on my plants, it’s showing up on all 3 of them. They are being grown in fox farms ocean forest amended with natures living soil. I have checked the ph of the water I’ve been giving it that is ro purified water I buy from the store and it seems to always be around 6.5. Although I’ve been measuring with ph liquid indication solution so it’s really just eyeballing what color it looks closest too and It could be somewhat off. It seems like the yellowing is worst at the bottom but also tips are yellow and brown at the top of the plant too. So I’m just mostly confused because it seems like it could be multiple things, maybe nitrogen deficiency or maybe nutrient burn of some kind. I just don’t want to try to fix it and end up making the problem worse since right now it’s not too bad. If you zoom in on these pictures you can see some of the tips that are burnt looking on top. Any help would be appreciated if anyone’s seen something like this with their plants or knows what this most likely is.

How old is the plant?
Have you been feeding anything besides water?
Are you checking pH / ppm of run off?

It’s 40 days old, no since it is amended with living soil I haven’t been feeding it anything other than water. Their website says that it is enough to take it from seed to harvest. I haven’t tested runoff ph I will do that when I get home from work.

Feed nitrogen...when the plant uses up what nutrients are in the soil it will start to take nutes that are stored in the leaves...working its way from the bottom up

Do the burnt looking tips on top also look related to needing more nitrogen.

No...burnt tips are from excess nutes...how long have tips been burnt?

I should have also asked what size pot you’re in.
The soil will only last from seed to harvest in a larger sized pot. 3 gal pot it’ll last about 25-30 days.
40 days into the grow it’s probably getting a little depleted, so I’d definitely say feed some nitrogen

definitely check the runoff, I had a similar issue on one of my grows where I would pH my water to 6.6 but by the time it was runoff it was MUCH too low. Switched to tap water fixed it. thats how I learned the hard way to check runoff.

Over all the plant looks pretty good...3gallon pot is kinda small in my opinion ...have you considered or do you plan on up sizing the pot at some point?...and or trimming some of those lower leaves and growth...prolly not alotta light down there...the plant will also shed leaves as it sees fit to do so...I really wouldn't trip out yet...

I would transplant into a 5gallon thin the plant out some for airflow and light penetration and I bet she'll be happier

tips started to look just a tiny bit yellow like maybe 10 days ago, and they just started to look more brown and concerning like 5 days ago.

Burnt tips are nutrient burn...she's pretty green n healthy looking really...that leaf that's yellowing is prolly in the shade mostly she looks pretty thick with foliage.

I trim all that crap off down there anyway...no light down there

As long as the tips don't worsen your good...I look for a little tip burn just so I know she's eating well

They’re already in 5 gal pots right now. I’ve been thinking about trimming the lower leaves, just trying to research how to do it and find some time. Yeah that’s why I wanted to go on here for some other peoples opinions I didn’t want to add more nutes thinking it’s a deficiency if it’s not and fuck up my plants lol. But this leaf definitely is below a lot of foliage so that makes sense. I’ll keep watching the tips, hopefully it doesn’t progress anymore. Thanks a lot for the help appreciate it.

Good plan...no problem

Don't be afraid to use the scissors...she can take it...and will bounce back and fill back in surprisingly fast...I tend to get fairly aggressive
