Looks like you have excess P and/or K. What are you feeding, what kind of medium are you using. Do you have an EC/PPM pen that you can test water going in and water coming out to see if you have a salt buildup.

Should I cut the dried leaves at the bottom?Should I remove the dried leaf in the bottom? I was thinking that it might redirect unnecessary energy to the plant since the leaf might be too far gone to save. I was thinking of starting topping next week as well, when the fifth node start to show more.4 years ago

Spots/decolouration on leaves: 1 sideplant (that I grow next to my growlamp) is getting a few spots....So, I have 3 plants:
- 1 centerplant that gets most of the light & 2 sideplants (left and right) who also catch a lot of the light, but not as much as the centerplant: the sides arent getting direct light, more reflective light.
?? The left plant is showing a few defects. Anyone?4 years ago
