Northern Lights and Bubblegum.

Based on a number of factors, I've relabeled the bubblegum and northern lights. I guess I did mix the seeds up (by being a dummy) - but all the profiles of each respective plants indicates a mix up. One is piney, the other sweet. One is early, the other on time for a 9 week finish. There's a lesson there. I hope I learn. 05/31 - Been giving only water to the Northern Lights (pH'd at 6) - Gave 8 L today to flush out nutrients. Runoff was at 6.5, 3100ppm(!!!!!) - but I haven't been watering till there's runoff the whole grow (fear of overwatering), so it could be collected salts and not a lock out (doesn't seem to be one to me...). Either ways, it'll be getting 8L a couple of times to wash the medium out. Will up watering quantity to other plants. With a runoff like that, I also wonder if my pen is off OR very surprised at the plants handling it with not signs of burning.
