Do these look OK for 19 days?

I got these clones at a dispensary. They were about three inches high in cubes. After transplanting into my bubbler they are 19 days old. The root mass is quite large. Right where the roots exit the cages they are kinda brownish but out in the tote in free water they seem to be the proper clean white that I read on here is healthy. PH is now 6.0 water temp is 64 PPM is 847. The photos make it look like there is yellowing but there is not. They are a very healthy looking dark to lighter green. Any thoughts?

Oh yeah, forgot one question. One appears to be a sativa strain and the other Indica. They're in the same enviroment and one seems to be a bit bushier than the other????

I travel for work so I mix it up and then leave those girls on timers for lights and fans. Last time I was gone for 12 days and they were fine. When Im home I'll change out the tote every 10 days unless my PPM gets outta hand. I'm using 3-2-4 organic.

The first looks to be Sativa and the Second Indica. Sativas are taller and lankier while Indicas are shorter and more stout, also Indicas can usually take more nutes compared to Sativas. I would try to clean it out once a week and make sure you have a large enough reservoir so they dont run out of water, they drink a lot late in flowering.
