Does the discolouring I'm seeing (looks dark purple) look like a deficiency or is the plant just using up nutes stored in the leaves? Please see W14 photos.
Heyy ccore! You have nothing to worry about there. That just looks like the plant doing its thang and changing colors as it get older plus the 10*f temp swing between day/night also helps bring this out in plants. It's a good thing to have that temp swing it mimics what it would be like outside.👍So nothing to stress out over this is a genetic thing some will do it more than others the plants look very healthy by the way nice job.👊 hope this helps! Happy Growing
