Looking nice! Don't underestimate your ability to make clones. And it's not really all critically complicated. Hell, I use some harsh-ass tap water, (pH well above 8, general and carbonate hardness through the roof) whatever temp comes from the tap, jiffy pellets which are according to some people too acidic and out of 12 cuttings I have lost exactly one. I use time-release miracle grow soil, insufficient lighting, excessive air temperatures, poor ventilation, and I always have results as good as I expect. Attitude has a huge influence, and there are people who do everything by the book perfectly and their grow fails miserably. Reminds me of a lady I did computer work for one time, her printer always broke down when I wasn't there. I think she was telling the truth, and that she simply had a crabby attitude which influenced her machine, as dumb as that sounds. Also you can separate two plants which are on top of eachother, but you should do it as soon as possible, not wait until they are big enough. I had the same thing happen and I dug one plant out with a spoon and they both did just fine. Maybe certain strains are way picky and give a little gasp of air and then fall over and die at the first sign of mistreatment but I would think that's a rare thing indeed. Main thing, don't worry, and your plants look yummy!
