Planet of the grapes

What's up guys, this will be the third grow I've logged on here. Last go I dialed in my rdwc system, this time I will be using the same system with some upgraded parts. The goal is to have my "harvest every 5-6 weeks" system in place by the time these start to flower. As for these gals, I have high expectations as the last two ethos strains I grew were some of the best bud I've ever smoked, let alone grown myself. The one on the left looks a bit rough, waited a bit long to transfer to the grow medium. Regardless, it is growing well and the root growth is about the same as the other. Now that I've upped the ppm and the roots are starting to reach the water, I imagine the growth up top will rapidly accelerate. Thanks for your time if you've read this far! Happy growing!
