Well i found out what happened .
My PH is always the same so I know how many acid to put inside it's always the same so I was a bit foolish not to measure it .
So 2 days ago I checked on of the bottles with water for plants just to know if this was the reason and yes.
My feeding water was only 4 PH so my plants got water with Ph that was to low that explains why it was not looking good.
Well it does not have seem to effect them to much and hope they recover from this.
Well that when you think it's not needed to measure every time.
