Red stems are from lack of any one of the three macro nutes. When the Def. is fixed the stems do not change back but the new growth will not be red. Looking at a long plant stem you can see the abuse it’s been through.


Jack, I thought you were quitting growing. What you some kind of not-quitter, huh!
What you cant handle quitting,
harris7 Reviewed by harris7 on . Mg def. ahhh! ok well i figured this would happen becuase it has before with other strains, i got some BB in week 3 of veg, i had plain well water at 300ppms with high calcium concentrate. I put some epsom salt in and it jumped my ppms to 500! so i got poland spring water and dumped that in the res, adjusted to 400ppms im at week 3 of veg so im hoping these ppms are ok but i can see now that the plants are curling at this tips and burning, the lower leaves are the worst. I would post pics but they wont help. Rating: 5
