@Gejlord, Yes! You're absolutely right. I made the mistake of initially underfeeding them, and then over-corrected and overfed and burned them. Yield/growth has been substantially affected because of that. On the plus side I know what PPM I should be targeting and dialed it in on the other grow I have going right now.
Hell yes on flipping to flower. On my Apex R1s I've been feeding at 1700-1800 EC in coco and they still seem hungry. Seeing the first trichomes! Looking forward to how your grow turns out!
I have definitely noticed that Apex R1 seems to be lighter in general on its leaves. Keep an eye on pH as well, I had a pH problem early on that I ironed out but am still dealing with the consequences.
@ThaDollaGenerale, Thanks! After the dry and cure all of mine smell like pine trees. I love it and I'm very pleased with the overall result. I saw you chopped yours too - I'm eager to hear what the final product is like!
