A buddy of mine has a small grow and he has some branches and stems turning white. He is growing in miracle grow with a small grow light. He is new to the business and doesn’t have answers to any other questions I have.
I’m with @MidwestGuy. If it ain’t broke don’t change it. From what we can see they look healthy. Some people get a decent run in that stuff. Some of us have a lot of issues in it. If it’s working for them then continue on. Great job helping a friend by the way! That’s part of what it’s all about.
I’m with the others. I started in Miracle Grow and my results were not so good. I’ve never seen white stems it could be genetic. Other than that it looks healthy
Just though someone might have seen plant stems turn white and have an answer. I will have to tell him not to worry about it.
By the way his and mine were clones together at the same time. The difference between good dirt, tent, good light, nutrients and pH.
Miracle Grow is extremely hot for cannabis. Some ppl have good results but very few. he may want to find a more pot friendly substrate. I’ve seen stems turn purple and red but never white. I say let him grow it out and see what happens.
