I am in no way trying to be rude, im just trying to get clarificadtion before. Ive read quite a few books on cannabis and have been a very active forum member and Ive never heard of Pest damage causing red stems. If you could explain this i would appreciate it, i just want to hear opposite viewpoints.

Let me clarify what i mean by red stems.

Red Leaflets, the steams connecting leaves to the actual branches, are very common in cannabis and don't really mean anything except for genetic differences. Next time you take cuttings you may notice that they start out nice and green and over time they may start to turn red while your waiting for roots to form. The plant is using its stored nutrients in order to form adventitious, while becoming deficient in the process.

A lot of plants will show spoty reddening on the main stems, but I have grown hundreds of plants and never seen one that had full on red stems that were natural. When i see red stems in my garden I know that its one of two things, a nutrient defiency or a ph problem(which in turn causes a nutrient defiency).

If you have a strain that grows blood red stems while still maintaining vigor....plz post pictures so i can stare i wanna seeAttachment 283429
