I need some help. I thought I had the beginning of plant burn so I raised my lights. I came home
from a few days gone and it looks worst and has begun to show in my other plant. I have now changed my diagnosis to under watering. What do you think? The PPM on both plants are over 700 closet to 800. The PH on both plants are just over 7 barely. I’m stepping up my watering. I’m still in the vegetation stage and have not been using nutrients because I transplanted from seedling stage. Any ideas would be great. Thanks.
If that is water caused I'd say over watering, but it looks like light burn to me. If you haven't topped the plant I'd top it below that burned top.
If I top it, basically it is cutting the main stem below the burn? After I posted I rethought my diagnosis. I think it is burn. It was already damaged and I think I am seeing the rest of the damage caused by the light before I raised it.
I was going to force the flowering stage before I saw the burn results. Any opinion on going 12/12 right after topping?
I'd give it some time to recover from the burn and the topping before switching. Yes you would cut it just above the next lower node. Highly doubtful that top would recover. Expanding the pic it looks like you two tops there in the center. If so just take the burnt one and let the other grow.
Thanks for the responses. I appreciate the help
