Brown/ yellow on two fan leaves

[GanjaGreg.]

So I’m 2 weeks into flower and I’m growing in FFOF soil.shes been living on PhD tap Water until the watering before last, I added some half strength grow nutes after spotting some yellowing on the bottommost leaves. Now I’m seeing two fan leaves of identical age on two different main stems ( I have a total of 8 main stems) that have a yellow/browning thing going on.
What does this look like to y’all?

You have some purple on stems but it doesn’t look bad. I’ve never seen purple spots on my leaves. I have had the purple stems.

Search showed purple spots on leaves as P deficiency. Learned something new thanks!

Being lower down on the plant it looks like P deficiency.

Either not enough/being antagonised by another element (calcium) or wrong pH.

If this is the only thing wrong I’d say not enough/being antagonised.

are they flowering yet?

@Nutty sKunK
Thanks for tuning in.
She’s 3 weeks into flower
Ph stays between 6.3-6.6.

I need to do some research on how calcium can antagonize P, some of that stuff goes over my head lol
Thanks for pointing me in the right direction.

She also dealing with a nitrogen deficiency.
I’m trying to figure out how much N to give her being that she’s made it through the flowering stretch.. I know she won’t need much, but still shouldn’t be showing so much yellowing only 3 weeks in to flower

Plants aren’t perfect expect blemishing on different part especially if it’s lower mature leaves.
I would add some supplemental cal mag and if anything increase feed by 10-15%.

I’m saying all this based on how robust the rest of the plant looks.

you got this buddy

I see your in flower!!! She’s eating more!! Increase 10-15%
