These are two of my seedlings which are two weeks old, in the past 24 hours they seem to have gone a yellowish colour which I know isn't normal at this stage of veg. My last res change was on Thursday, none of the roots were in the res's back then, but a week on they have all made it there about 4 days ago. I did have to dilute the mix a bit as it seemed to be a higher ppm reading than it was when I initally made the mix.
