Forbidden runts 420 fastbuds

Think im getting the hang of this dwc thing. Week 7 is looking great. Switched to distilled water as my well water was taking 20ml of ph down to reach 5.5 on 6 gals of water, and would climb to 6.5 in 24hrs. Been giving them too low of ppm also 600 would drop to 350 in 24hrs. Raised it up to 900 and now plants are happy all the time. Thanks for checking in stop in next week 👌
