Great work so far! I'm on my first grow too and I'm impressed!
You cropped your plant to look like a beautiful REEF!
I see the same purple in my plants, and I know the plant isn't purple kush or even related.
Were you able to get rid of the spider mites with just alcohol and water?
And the way you topped and cropped your plants is awesome! Keep it up and I'll be watching.
I see how you covered your clay with foil I was thinking of doing the same!! Making a skirt to keep the roots from light correct?
Also I'm wondering what happened your first attempt? It certainly seems you've learned from your mistakes. Good luck on veg. I'm using a LED similar to your mars but Vipar spectra. Was thinking of adding a UVB at flower stage.
