I currently have 4 vegging plant i feed them at 450 ppm at a ph between 5.8-6.0 ...but recently i noticed some of my stems turning red and im not sure why. Any input would be appreciated...thanks in advance
I had some red stems early on , I was told it could be cold weather or be needing some cal-mag . We did have some cool overnight temps ( outside grow ) and I did add cal=mag and the red stems went away . Alos some strains tend to have some red . Your plants do not look unhealthy to me but im new also
Main stems or leaf stems..? Leaf stems red/purple are normal with certain strains..Red/Purple Main stems are usually temp/ nute problems..
