The goal is to reduce the stretching that is done early on in flowering and tighten up the node spacing. Another thread here in basic growing called "23 days of flower blah blah blah" something like that... we started a discussion about the use of MH during flowering. Check that out when you get a chance, its experimental theory to me, but someone else seems to be having success with it. Once you get the PH meter and more pictures and such it should be easier to fix your plant, shes looking healthy though for the most part. Keep on it.
Well i discovered that mh actually out uv rays, as i have transition lens glasses and it darkens them in 2 seconds. As you probably know the tricomes, or however you spell it, of cannabis are a defense against uv rays and herbivores mostly. So more exsposer to uv might mean more tricomes= more thc.
