HELP: What's Happening to my plants?!?

[NatalieSmith]

I have had 3 successful harvests and now I am on my 4th. I have not changed anything with my process.

All of a sudden several mid-level leaves started turning yellow and now there are rust spots.

Check out these pictures...

What do you think might be going on here?

Any help would be greatly appreciated.

looks like a nitrogen def my man very normal during flowering but usually doesnt happen til its close to harvest.

fan leaves naturally die off during flowering , nothing to worry bout man looking good

 

[NatalieSmith]

Is this really alright? This didn't happen during my last 3 harvests. Why is this happening now?

Look at the rust spots... is that normal?

you need to check your ph run off, your probably swinging very low

 

[newb101]

have you changed anything this go round?

 

[Mr.Organic]

could we get some better pics of the leafs with the spots

 

[supdro]

if your ph is in range and the water is full and the ppms aren't too out of whack it is one of those two i would think.

may be a nute problem, or ph but im pretty sure you dont need to worry... its a natrual part of its life... they are putting all there energy into flowers so a few leaves will die

What does ppms stand for? These plants are only in the second week.

parts per million-ppm a measurement of particles in water

i thought that only applied in hydro not soil??

 

[NatalieSmith]

Do you think that it might be caused by water contamination?

What do these yellowing middle leaves and rust spots normally indicate during a soil based grow?

had same thing happen on my 3 week old plants because I didn't think they needed nutes. Once I started nutes, yellowing faded and no more rust spots. Def a nute or ph lockout issue, good luck!

 

[Dr. Haze]

what type of nutes are you using and how much, it coud be a defincency or a slight burn, also possible that a bug has gotten on to it
