Is this a burn from the light?

This is my first grow. I have 3 plants, the two tall ones (hawaiian snow) are more yellow and crispy than the short one (early durban). The edges are yellow and crispy. One had it on one leaf for quite a while, and now they all seem to have it. Even the short one has spots of it. The temp is only 81.5, and they're about 20" from the light right now, they were about 12" before I moved them.
Anyone have any suggestions?

What kind of light are you using? Those look like heat stress to me..but I couls be very wrong....

It looks like the first pic here, which is heat stress https://www.rollitup.org/marijuana-plant-problems/157345-have-plant-problem-check-here.html

hmmm......i've had something similar going on throughout my current grow as well. what kind of soil? are you using any nutes at this point? how big is your light? what sort of water are you using? are you growing in a closet? are you using foil?



i assumed my problem was nute burn. my bubbliscious were most effected but the narkush and k-trains had some of it too. however, i'm about one to two weeks from finishing and even though some of the leaves still look like yours the plants have turned out nice. maybe you'll be alright.



i'm trying to figure out how to send you a link to my current rollitup grow journal in case you're interested..... i think you just click on this:
