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.

I had similar damage on a plant before because my heater was too close. Do you have a heater in your tent? If not, must be light burn. What light are you using and how close was it to the top of the plant? Also, where is your fan placed?
