Is there anything different about the plants with the symptoms and the plants without? Is it happening most to the parts of the plant that are closest to the lights? I've noticed some plants are a lot more sensitive to light and heat compared to others. Sometimes some plants are fine while others react poorly in the same conditions, especially Indica leaning strains.

When you put your hand where your plants are under the light, does it feel too hot after 30 seconds? If it's too hot for you it's usually too hot for your plants.

The other thing is have you been checking the pH? The pH being too high or too low is the number one reason people see deficiencies.

If you changed their nutrients right before you saw symptoms, that is definitely a likely suspect, too!

Thanks for responding nebula it happened in both the veg tent and my flower room got to be the chemicals and not the Heat so I obviously goofed. Love the website you rock.

if the plants that are/were affected are ones that were closest to the fan(s) then you might have a wind burn issue, maybe combined with any of the others mentioned above. I had a plant that looked like that my first grow and it turned out it was just too close to the fan. The new growth got a lot better when I moved it into the opposite corner. But the damaged leaves never healed. If the problem continued after you moved it into the flower room then it might still be wind burn_ if that is what initiated it. Those leaves are too damaged to heal so moving them to the flower room wouldn't fix that. It took almost three weeks for that plant I had to heal and it added three weeks to final harvest as well.
