Why is has my plant gone purple when flushing for harvest

Hello it is normal because your strain is bluberry. It is genetic. With these strains they got colors easily when you have variations of temperature. So don't worry your plant just will be more beautiful. Bye

Thank you. I forgot to mention my grow is in coco. Do you have any advice on the PPM and EC as still High

Yeah some plants just do that. You say you’ve been flushing for 9 days already. This is completely normal. Since your flush started. She’s hungry. So no food means she’ll eat her fan leaves to eat to make nice buds. My blue jack (Jane) did the same to me. But I think my environment and growing conditions had a little play in that as well. Though by searching other blue jack grows their leaves also turned a slight hue of purple. So yeah as shitty as you don’t want it to happen. It’s just what it is. I would just enjoy the harvest. Look at my notes and try to see what I can do better next time. You don’t show much so it’s hard to say with no diary to look at, but I’m sure you have some nice bud to harvest. You have a good flush going on. It shows that there’s really no nutrients left in the plant. Should be some smooth smoke. Enjoy your harvest. 🤙
