Small brown spots on certain leaves
Some leaves are showing small brown spots. Around 5% leaves affected and all are close to each other. Can this be an infection? Otherwise plant looks healthy

Upward Curling Brown Leaves/Nutrient Lock Out?
I've got a serious issue. Started 3-4 days ago, right after adding nutrients and increasing light. Leaves are curling upward and browning. Not crumbling yet but look like they will be soon. Both new and old growth is being effected. Maybe the Mineralized Phosphate was too much.

Brown little spots on leaves
Hi, I went on vacation for 4 days, the ec went from 1.2 to 0.5 and many small dots appeared on a lot of leaves. Do you think it's due to that ? The ph went from 6.2 to 6.4 but I don't think that's it... Thank you for your answer :D Peace

Is this turning purple from temp change
So it looks like what I thought was a brown spot (under the grow light), appears to be purple when I pulled it out to get a better look and stake it down. I did switch the light to something cooler, could this be from temp dropping. Not worried yet, just curious. Thanks
