Why are there brown spots on the leaves?


Something wrong with your water. Red stains on everything is bad.

Id terminate the grow and deep clean


Have you put some extra nutrients into the tank? Something beyond the regular nute bottles?
Like @Todd.grobo said something looks wrong with the tank/water. There is way too much “red” staining for this early in the grow. Also there is quite a bit of gunk growing on the plastic sensor guard.

Is this your first grow with a new unit?


If you wanna try to save her…

1). Drain & clean.
2). Cut the roots where you see the red begining and the white roots ending.
3). Refill
4). Dont add anything to your water except 3 teas of hydroguard.
5). Keep an eye for the brown spots moving onto the new growth.
6). Cut off leaves with brown spots after your plant grows another set or two of leaves.
7). Post again if your unsure or need help. :eyes::seedling:

P.s. Your new growth looks healthy so its possible this could be a nutrient stain. Always post a pic of your nutrient bottles and a list of any additives you’ve used. :eyes::seedling:

For all plant support questions, we ask our growers to please provide the following:

  • Pictures of your plant. Please take pictures with the photo mode enabled (Hold the button on the back of the unit down for 2-3 seconds then release for photo mode to activate) and upload them to your GROW JOURNAL in the Grobo App. That way, they won’t get lost in transit. {:white_check_mark:}:

  • A picture of your plant’s roots. Simply lift the lid a couple inches, snap a picture of the bottom of your coco pod, and upload it to your grow journal. {:white_check_mark:}:

  • A picture of your plant’s stem. Simply lift the bottom canopy to reveal where the stem meets the coco pod, snap a picture, and upload it to your grow journal.

  • [(#ShareYourGrowJournal): {Search :mag:}:](Search results for 'grow journal ’ - AllGrowers Forum | Hydroponics, Harvesting, Cannabis, and more (

  • What type of water are you using? RO, distilled, tap, other? {:white_check_mark:}:

  • Have you made any modifications to the unit or environment? (i.e. Add a chiller to your tank, humidifier to the room)

  • Have you added any supplements to the reservoir? (i.e. Hydroguard to fight root rot)

  • Have you adjusted your schedule at all? (i.e. Shifted a stage, added more time to a stage)

  • Have you cleaned and calibrated your pH probe between grows? If this is a new unit, it will arrive calibrated. If not, a calibration in between grows is necessary to maintain your probe’s accuracy.

  • Please let us know, and we can then combine your answers with your data to get a clear picture of what’s happening.

Glad you resolved it, hate too see it come back and kill her in flower :blossom:


Hi. So brown spots probably indicate that you have issues with micronutrients, particularly calcium. Baking soda should help but check online to see how much you should use per the amount of water you have.
