Autos with Dr Earth and Coco

Done with week 6. Weekly thoughts... * tried upping the light level to 16k+ lumens. This caused some light burn, I think. You can see the tops of those leaves ends. The reason I think it's light burn, not something else, is cause the bottom leaves don't have any signs of issues, only the ones in the light. * I have tried reading about light levels. I don't have a PAR meter, only a lux, so I'm trying to do what i can with that. I've read calculations to convert from lux to par, but not sure if those are valid. My light is less than 1/2 power, 3 feet up, so not sure what it should be set at. I'm trying to listen to the plants, and I turned it down when I saw the light level. * my ph meter broke too and I think I had a ph issue early on. My water was probably around 6. The leafs were starting to turn lighter green. This was tested using the drip solution. I got it back to 6.5, and they seem to be a bit happier. * I started watering every 2 days, with about 30-40 oz. Getting too dry otherwise. * the flowers are starting to form nicely. * I think the FastBuds started flowering about a week before the other two. It has much more developed flowers compared to the other two.
