I need some support...help, please...I'm so alone..........

I'ts my first time growing. I'm an old hippy that needs medication for chronic pain and I need to grow it myself, so here I am. I have a nice set up, 1000 HPS light with rail, 8' x 7' room (Coated the walls with a thermal protective white gloss), using the Earth Juice line for feeding, earhth worm castings sprinkled on top. My plants are now 2-4 feet tall and budding beautifully. So, here are my questions. My mentor said that I need to replant a few of the plants into larger containers, is this safe at this stage of flowering? And, what about spraying? I have the EJ essential spray, Vitamin B-1 and Neem oil that I have used in the veg stage, but I keep getting a mixed message about spraying in the flowering stage. Should I be spraying? And if so, when and how often?
And I want to pass on this on...AzaMax for spider mites is the bomb!

Well look at it this way, if you spray the buds with fert water you could then smoke it later. I don't, but thats just me. As far as re-planting it wont hurt the plants, but why unless you want them bigger. In outdoors yes, but indoors you arent growing to get them large.

From what ive seen, it may shock the plant a little bit but in the longrun you just wait a little longer and it will be a lot better for the plant if you transplant it.

Thanks. I'm really just a little lost trying to remember everything. My roses never took this much care, but I didn't smoke them. I've got white widow, blueberry, purple urkle, and white shark strains. I've had nothing but trouble because my mentor up and left the state without telling me much of anything. Spider mites, ballast quit working, light rail came very late, so I was moving the light all day, but I have a crop Thank goodness for the plant store I go to, the young man that helped me knew exactly what I was growing without being told and he hooked me up with stuff, but I had the plants growing for 2 months before I even knew I had to check PH and contaminants, let alone feed them any different from my other garden plants. I can't wait for harvest, because the next crop will be KUSH!
