Looks like you did a great job. Thank the powers that be for this technique. You gotta at least top the indoors, and even then they can go wild. I tried a method of topping called FIMming. Supposedly it stands for "Fuck, I missed." How apropos.
Out of 20 girls I hit the spot on 10 of them and each one had 4 (or more) tops. No shit, 4 mains. It's kinda a bitch to get it exact, but dammit man when you do...
Fire yourself up a spliff and chill. Not every single thing you perceive as being wrong is a problem. Study the plants. (I sit in the room sometimes for an hour or so and watch them) They are living things, and as such will have some "individualities".
Plants are living things. like us, they're gonna have "freckles", "birth marks", red hair, blond hair, etc. You get the idea.
Yes, purple stems CAN indicate some sort of deficiency, but almost every one I have grown has had some purple stems to one degree or another and had no apparent bad effects. Out of all the probs I had, the stems being purple were the least significant.
Cannabis is a plant. That's it. Nothing more. You probably grew one in the 3rd grade (lima bean) There is NOTHING arcane, mysterious, or magical (OK, Ill give it magical) about growing this plant. There are certainly some things you can do to boost the yield, and harvesting at just the right time makes all the difference in the world for potency. Just do it. Don't try to be Jorge Cervantes your first time, you most likely won't do it. Get the basics down then refine your system.
Just worry about getting them thru to harvest this time, Each grow is the result of what you learn from the last. get a few grows behind you and you'll be fine.
I was my own worst stumbling block. I can grow about anything ornamental, but when it came to growing pot, all the urban legends, myths, and plain old misinformation came to mind. It was like someone took my green thumb off with a cleaver.
