31 days into flower...yellowing of fan leaves(pics)

[Muffy D]

Im 31 days into flower and all the fan leaves are quickly turning yellow. I was told that the yellowing of leaves is normal during the end of the flowering stage, but at this rate it seems like they wont make it until the end. Maybe Im just paranoid but check out the pics.

That in hydro or soil? What kind of nutes you giving it?

 

[FilthyFletch]

Well...what's your ppm and ph? When was the last time you did a changeout?

I just changed the nutes 4 days ago. My ppm is at ~1100 and I keep the ph between 5.8-6.5

anything higher then a ph of 6.0 yur way to high and that may be your issue right there. You do empty the whole res every 10 days and thenstart fresh correct?Do you have the res temps monitored? You want the water to be around 65 degrees F no more then 70 max as that will hurt the roots and the nute uptake which can cause the yellowing or worse root tot then the plants slowly die.Try adding so grotek h2o2 tot the res about 3-5 drops per gallon every 4 days

I read a swing in ph is good because different nutes are available at different levels, but judging from your thousands of posts on here, you know your shit and ill take your advice. Yeah I empty it every 10-12 days. I have a res chiller set at 70. What does the grotek h2o2 do exactly? I bought this stuff called subdue...and it is some organic pythium gaurd stuff that makes soapy bubbles that really kill any rot going on.It came in a tiny vile for about 30 bucks and Its used at about 1-4 drops per gal. If I use the h202 wont it kill the benificial oraganisms since my nutes are organic?
