Looks like heat/light burn to me. I good indicator of this is when your leaves start to “canoe”. Either move your light up, or decrease the intensity on it.
Lightburn:
Yes. I had to re rig the long hangers that come with the light and that gave me about an extra 3 inches. At this point there is very little vertical growth. All energy seems to be going to the buds stacking up.
Just noticed another bud on the lower plant starting the same thing. I just flushed and once it dries out I will add nutes back along with some epson salt.
What are you feeding her ? I don’t think it’s your LED light. I have a 1200 watt LED, and I hang mine about ten inches from the girls and never got light burn. Looks like nute burn to me, but I will be interested to see what the experts on this site have to say about it. She doesn’t look to bad, nothing some good advice, and TLC, won’t take care of.
I don’t think it’s lighting either. Feeding fox farms trio at half strength. Could be lockout so that’s why I flushed it and will try feeding again in a few days
I was growing in ff soil then learned it wasn’t enough nutes for the whole grow. I got bad info on that. I have only fed 3 times since getting the nutes. Started off a 1/3 then increased to half
If you are watering, and or feeding three times a week, she might be getting to much water. The soil should be dry to the touch before watering / feeding. Also, you will need more light when you go into the flowering stage, I have a 1200 watt, and I plan on getting another one for my next grow. My indoor plants grow in a 3 x 3 x 60" tent, you can’t have to much light for big bud growth.
