Spots on leaves

@Stephen My Bubblegum seems to be growing however there are spots on the leaves .


Its seem’s to be only on the lower leaves… this is pretty normal… it happened with both my first 2 grows


She looks very good to me. :slight_smile:


Might be nutrient burn happens all the time looks healthy


I don’t believe those spots to be nutrient burn. Check on the underside of the leaf for bugs. Also, can you take a pick when the light different so we can see the color of the spots? I could be wrong but I think you have a micronutrient issue. Maybe calcium or magnesium deficiency.

I had my Grobo in the bathroom my first attempt earlier in February, and my plant died after a month. Turned out that the bathroom temp was simply too hot for the unit. Now, it’s in my air conditioned kitchen/dining room, and this new grow is the happiest I’ve seen ever.

Room temperature and air conditioning makes the absolute difference.

Happy improved gardening! :broccoli:
