Day 5 watering/light feeding (see planned schedule above). Pot took about 400 ml of water. Watered very slowly PPM of water was 250, and pH 6.9. Run-off PPM was 650 and pH was 5.6.
Is the run-off difference normal?

Also, built mylar-lined aluminum reflectors for the CFL bulbs. Almost double the light compared to the bare bulbs.
