Just trying to help sorry i didnt read that line...i just thought you wanted a good organic mix...if you can find that stuff you can find bat guano i would think
The bark is not what uptakes nutes its the white inside but again you should be fine just dont mess with it...i pulled the tape off mine before it was healed then it just bent over again
Thats what i was going to say. Less yield as they flower with 18 hours of light so if they get 12 hours thats like 1/3 less light then they are used to.
