How can I stop these brown spots from appearing on the leaves
You can check your nutrient bottles or send a pic so we can!
You can calibrate everytime you start a grow.
You can remove the bottom leaves to cut down on moisture and bugs.
You can mark your nutrient bottles with a marker so you can keep track everytime you drain and fill, great indication of when ph is off!
Finally when all fails you can send in a ticket to support!
Hope this helps! Repost if you need more help!

A low relative humidity will cause a cal-msg deficiency. Check your Rh!

I can see your ph was off because #2 shouldn’t be lower than # 3, 4, or 5.
Two reasons why this may be is…
- need to calibrate probes.
- using the wrong water.
Two would be my first guess!
Are you using Reversed Osmosis or distilled water ?

Ok good to know! Start marking the bottles with the marker now so that after your next drain and fill we can see how much is being used!
