Help me diagnose

[Pmurp]

Hey everyone, I’m on my 18th day of flower on my second grow and it looks to me like the leaves are turning yellow.

I first noticed a pigment change on the 16th (4 days ago). I’m growing in FFHF (yes I know now FF soil isn’t great).
I thought it was possibly a nitrogen deficiency, so I watered with Nutes (big bloom and tiger bloom) 1/2 strength
Pics provided, if more are needed I’ll update at 9pm EST. Thanks

So you think you have an N def so you add more flowering nutrients that are less in N.

makes perfect sense lol.

I was under the impression that big bloom was the highest nitrogen of the trio? Would you agree that it does look like nitrogen def? What should I do to correct it then

Heres what you do double check the moisture levels once needing a good water hit them with some dolomite water drain to waste 10-15%!!they’ll be fine in 3 days if not sooner.

How often are you watering?

how often are you feeding?

To me it looks like you could have a lockout

I’m not soil guy though so I don’t often comment on best practices for your medium.

If you’re not feeding with Grow Big then you’re not getting much N. TB is like 2-8-4 and BB is only P and K. You’re also in a stage that uses/used a lot of N.

Yes grow big is 6-4-4 or something
