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?

Hey hang in there,hopefully sum 1 with more experience can help u, i'm having same issue with 1 of mine also using ff soil hf tho, i'm praying it isnt tobbaco mosaic virus ffs
 
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

thanks man I didn’t even realize these were purple spots until you mentioned it!
I thought they were brown:bigjoint:

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
