I think these are the pics you're talking about
they are 2 pics before the link you gave.

Looks like a nute issue.
Next 2 watering cycles, plain ph balanced water, you should see a change.
Start her back on 1/2 nute strength.. Back to normal as she gets stronger
Good luck with your grow. Hope this helps
