Deficiency?

[Tillyoudie420]

Hey friends, I’m on my 3rd grow of the year.

This is a new strain and had been growing extremely well up until this week (week 5 flower) I seem to be having some bud sites showing deficiency signs... new fan leaves are coming out yellow and thin. This is only on a few satellite branches that popped up through my scrog and not the main colas. I attached photos of the problem as well as the other normal looking colas. from my own research I’m leaning iron deficiency but wondering if anyone else has any ideas

quick setup rundown
3x3 x6 tent
FFOF soil in a 3 gallon smart pot
FF tiger bloom / cal mag
1000w Mars hydro LED
Enhancer co2 bottle
Scrog

I don't mean to alarm you but that looks like the time I had budrot,
If you can just try to open up the area of the bud where those sugar leaves have turned, if it's smelly, slimey and sticky it's going to need cutting out.

Hopefully I'm wrong but it's worth checking.

I considered that initially as well but my rooms RH has been at 40-45% at most throughout flower I actually had to add a humidifier because it was getting as low as 32% at times

If you gently bend the bud you should be able to check inside it, hopefully it's not rot but if it is you want to catch it quickly.

My flower tent sits around 40%rh but it was my fan tripping out for 24hours that i think caused me a problem, you need some real good airflow across the buds.

Just took a peak, seems normal on the inside when I open er up .... I’m wondering now if it’s maybe potassium deficiency from salt build up ? Going to try flushing tomorrow
