1st grow Sweet ZZ Auto RQS and Northern Light Auto RQS

Still no nutrients this week. Great growth and I stopped using the tap water at the end of the week. I started using store bought Primo water which is reverse osmosis treated. 7.99 for 5 gallons and ppm tested at 30. I add 1/4 tsp of cal/mag which brings the ppm to about 150-180. I flipped both lights to 50% and raised them to 25in above the canopy. The Sweet ZZ (plant on the right) has been quite a bit ahead of the Northern Light. The Northern Light has been kinda stout.
