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?

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. :bigjoint:

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 flowerD6F51B69-965C-4FFD-938E-846DFD9388E2.png

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
