Hi All High Brixers. My first grow (out of college) is coming along spectacular. I cannot believe I didn't do this so long ago! Anyways todays question is about stem color. My plants ( I have 2 of them) look awesome. One of them is green all over, but the other has these insanely purple stems--which seem to get more purpley everyday. She just had an energy drink about 6 days ago and i'm getting ready to re-charge the soil. Is this purple some type of magnesium efficiency? Or should I leave her be? Pics below...Thanks!!
I think everything looks great! The pics you shared don't show that much purple, except on a couple petioles. It could be several things:
1. characteristic of the strain...only really high brix readings will show green everywhere on some strains.
2. Cool root zone inhibiting phosphorus uptake and decreasing microbial action. Get the containers off a cold floor or slab if they are on one.
3. The need to feed, especially foliar feed
But seriously, your plant has perky leaves and good structure. You're going to have a nice harvest for sure. Well done.
What kind of lighting are you using?
