Nute burn or n def maybe?
    #659346 - 02/17/13 09:12 PM (3 years, 9 months ago)

Leaves turning yellow but getting darker green.


The ph of my water was high for a few days... like 6.5  and the clones started to look sad.  Adjusted ph to 5.6 and added advanced a/b.  Leaves got greener plant started to grow bigger and now I see this sharp yellow on the leaves.  Other than this plant seems healthy.



Thought maybe n def cause by nute lockout from high ph for a few days?

maybe nute burn?  though my ppm's are pretty low.ans ?'s below and pictures

TY man...  Thinking it may have been from nute lockout due to ph being way to high for a few days.

Possibly.  Your in the time period grow wise that it starts to show up.  Either add a couple teaspoons Epsom salt per gallon, or up your main nutrient depending on what the content read out it is.
