Mandarin Cookies - Ethos - DWC

All depends how you want to grow. some people do both others don't. If you having multiple issues I would suggest a new batch till it can be stabilized. If you need any other help reach out via DM "Direct Mailbox" its the little paper airplane logo/tab on the bottom right hand corner of your screen. Cheers,

Measure every day and adjust pH and EC every day. Then do a full clean with fresh water and nutrients once a week. Because the plant will leave more from the nutrients that she doesn't need that much compare to the one that she is craving for that time. So to avoid a high EC on nutrients that she doesn't need as much and provide her with the ones that she is using the most do a clean once a week.

I will definitely do a complete bucket change after the first week in DWC... I find the clay pebbles, as I top water during that week, put a lot of sand in the bucket even though I've thoroughly rinsed them before using. Thereafter, it becomes a judgement call - if I have to raise the EC (or lower it), I might withdraw 1 gallon of water and fiddle with that and put it back in... or if the pH is not staying stable I'll do the same thing... Plants don't usually end up drinking a whole lot until they get to pre-flower/flower stage so just adding a bit of adjusted nutes to top off is generally fine but EC requirements change week to week and I often find it easier just to do a complete bucket change. When they start going through the water heavily, I will then definitely start changing out the entire bucket once a week... ALWAYS clean your bucket or reservoir out with a good dose of hydrogen peroxide to ensure the bucket is clean and free of anything harmful... Good luck!
