Its pretty normal to have on the main stem when they are young, almost like they are shedding a little skin. Next time get some good soil, you have to be extremely careful with MG, you can burn the shit out of them if you over water even a little because of the time release nutes. Yours look a little burned, and hang dog.2nd try. MG organic soil.2-65 watt fluorex lights, 1-15 watt GROWL-LUX led. Got something that looks like scotch tape on stem. Any thoughts?
hey I appreciate yall's time.^^^^ yup... perfectly normal.
