The good news is, you're learning about growing and recognizing issues, even if they were allowed to progress further than ideal. The other good news is that even with limited height, there are still actions you can take.
For your immediate issue (which is definitely light stress):
- While you can't raise the light much, raise it as much as you can and lower the intensity by dimming it.
- You can also gently bend the branches away from the light. Do this very gently and carefully to avoid breaking any branches.
- The leaves that are burnt will not recover, however you may be able to limp the buds along to the finish line although quality and yield will likely be reduced but you'll only know if you try!
For your next grow:
- If you have limited height, try some training techniques like SCROG, manifolding, as well as some low stress training (LST) to keep the plants more bushy and spread out like a tabletop.
- You can also find strains that are shorter so that you can combine a strain with a shorter stature with the above mentioned training.
- For planning purposes, start with the end in mind. This means that now that you have the experience of plants growing into your light, you'll be able to take lots of small actions at the beginning of your grow to prevent this issue from happening again.
Things happen to all of us and that's how you learn! Any sort of recovery of these plants will take some time but all hope is not lost! Hope you keep us posted with how the rest of the grow turns out!
