2 Northern Lights Autos

So this is end of week 2. The c99 x blueberry fast is growing well - didn't traumatize it like the northern lights autos so I feel that's why there are no deficiencies. The other two I'm not sure about. If you look one has brown spots on the lower leaves - not sure if its manganese or potassium, I'm leading towards manganese since the tips seem fine. I will admit I got pretty anxious and fimmed both of them then tied them down just to get the pain all over with at once, she seemed to like it because the 30 hours later she has shown growth - I did give them a nice feed about 20 hours before I did it. At the start of week 2 I finally got enough water in them to get 10% runoff - the ppm was 675, and 355 going in. At the end of the week I decided to give some it RO water with algamic and cal mag both around 4 ml each in 1 gallon, after testing the runoff wa sdown to 475. I'm into week 3 now and I plan to up the nutrient ppm content between 700 - 800 because I know Indicas like higher ppm (more food). Any suggestions please don't be afraid to comment and help me out. Peace!
