    Brown spots on leaves - newbie grower

    I'm a new grower. I've got 3 autos in a tent. 2 are growing fine, no issues. This 3rd auto developed brown spots on leaves about a week ago. I could use some help trying to figure out the issue. Lighting and water the same for all 3. This is my 2nd grow and 1st plant with issues. Damn...

    Hi jamesphoto it would be helpful to know more about your setup and watering, pH and such. Maybe a pic of the whole plant and a sister to compare.

    How big is the pot? It looks like it is either root bound or you have a pH problem with only one of them for some reason.

    Did it pop normally, was it a slow stater?

      Your pH is out of whack. Adjust to your medium's requirements for canna.

        could also be a calcium deficiency if it's just the upper leaves.
        I hope there is an afterlife...there are a lot of friends and family I'd like to see again, one day.

          Thanks all. Catfish22 this was growing in a 2 gal fabric pot. I made the mistake of buying a 2x2x4 grow tent (I wish it was bigger) so I'm trying to keep my plants short. It was growing in Happy Frog soil. If I'm reading the pH correctly it is between 6.0 & 6.5.

          This is pretty much on top leaves and bottom leaves. Odd that the other 2 have no issues being in the same grow space and the same water. This one was the black sheep of the 3 - was a slow grower and the smallest of the 3.

          I cut it down yesterday. The buds were small and just starting to change pistil color. I was scared it might pass something on to the other 2 so I got it out of the tent.

            Yeah, sometimes it's better to just cut losses. At least you have the other 2. Good luck!
            Happy farming!🙂

            PS: How did the root ball look on that plant?
