Im 6 weeks into flower and been having problems for almost two weeks with yellowing leaves. Last time I posted I got ten different answers.and I watered with nutes, and it actually cleared up a bit. But looks like shit again today. Is it a nitrogen Dec.? If so how can I fix this asap. Bud growth has seem to slow down to much

It does look like nitrogen, iron, or sulfur deficiency, what are you growing in? specs?

Edit: or zinc, possibly

could you take something a little closer up and describe the progression from the point you first noticed a problem to now?

might be calcium deficiency with some lockout; not sure about hydroponics sorry friend, but i do believe your pH is a little high, but, again, i dont know about hydro.
best of luck to you.
:peace:

I see some clawing on lower fans which suggests overfeeding.
Maybe you overdone it when trying to correct yellowing last feed,and now caused a lockout.

What you think I should do. Flush?

I normally feed half current strength nutes rite after a flush so the plants have something to eat.
Ph to 5.5 as i find that ph always goes up in coco and once it gets past 6.2 your plants cnt absorb much.
I would add some cal/mag too,coz as you will know,coco has a tendency to hold on to cal/mag.
I only use nutes in the last litre of flush per plant,always works for me.
Good luck with your grow mate.

From your first post it sounds like you dont water with nutes very often. So I doubt you have a problem with overfeeding. Would get a lot better advice if you told us exactly how you had watered them for the last couple weeks, frequency and amount of nutes.

The yellowing looks like lack of nitrogen. You said you're using GH so I would bet that this is a N deficiency. I used these nutes for the start of my first grow and had similar issues. Try something better like dynagro or jacks classic makes some hydroponic nutes that I think should work in your set up. If you have to keep using the GH use whichever one has the most N (cant remember which that is called).
