Hello all, I have a few questions on my current grow and when to consider harvest. Even though all of my plants have been started at the same time they seem to be developing at different rates. All of the plants are in the same hydro system and the one listed below which I call Fiona (Shrek's bitch) even though it started great, it appears to have stalled completely and some yellow leaves where the others do no not maybe genetics possibly. i'm not sure on whether to let it go or harvest and get what I can. On this any advice would be great.

On my other 3 plants I'm also a bit confused. two of the plants appear to have to go at least 4 more weeks, but the other has many red hairs that appear to be getting redder see below:

Sorry for the black lines in the pics, the light is rough on pic taking. As I had stated earlier I know 2 of the plants have at least 4 more weeks, but Fiona and the one with red hair (Helen Reddy) look to be close...can anyone advise?
