i would look under those leaves.. for creapy crawlies

if its not them, then maybe someonelse can help

I'm thinking it might be "spray & grow" when the lights are on them?

im with ileso, kinda looks like tomato leaves when you get those little caterpillars, but i doubt those would be in your grow room.

have you been spraying them? i cant figure out the reason for the spots. im inclined towards some sort of bug, thrips or whiteflies.. dunno, something that sucks cause its what it looks like from my experience. but if you say you sprayed em then it could be that. spraying leaves when the lights are on can burn them...

hopefully an experienced indoor guy..or gal will help here...

Hi Munchies,
One day I was trying to foliage feeding my plants and I misted the leaves on the above side with the lights on and let it that way, and next day some of my leaves were like those of your pictures
If you have not misted your plants in any way if I were you I would try to check the down part of the leave to see if there is any insects in them
Peace

I Had some leaf's do that, and it was because i gave them to much food or to much molasses, anyways, i stopped the feeding for a week , and the next 2 times i just used water, to kinda flush it out a little, and she colored her self on out,
some still had spots that began to fade into a reddish'orangish color,

i cut them , she lived, everyone was happy

so maybe you over fed?

if it continues, and if it's in veg or flower, i would gohead-n-cut it because , energy will be used to repair the leaf', taking a while to complete, thus for , taking precious energy away from ur growth.

In my opinion anyways,

MJ is a survivor,a few snip's here and there won't hurt nothing!
Think of what all they go thru outside,
Dont stress it , just let her work her self out of it, she'll come thru stronger
Good luck,

I'll flush the tank and do a three hour Flora Kleen and also stop the misting, see what happens.

My rooms pretty much sterile from the out side, even have a fine filter over the fresh air intake and it's only one plant out of the four.
Thanks

It Kinda Looks Like Spider Mite Damage, That Is What I Would Check For First. If It Was From You Spraying With The Lights On?, It Would Look More Like A Burn.

Just the upper leaves on one plant out of four, don't see anything on the under side

These examples would be true spider mite damage, not what I have, much different.

If There Are Mites, Some Time It Takes A 30x Loop Or So To See Them. When I Had Mite Troubles, They Were At The Top Parts Of The Plants, & Some Plants They Didn't Bother, & Some Plants They Were Attracted To The Most.????,,,Have You Looked Through The Plant Abuse Chart??
Here Is Mite Damage On A Soybean Leaf.
This One Is From Radiant Heat.
Radiant heat is also called “light burn”. Typically, topmost leaves will become pale green, then turn brown as the burn progresses. Plants on the outmost edge of the garden will remain a healthy dark green, with light burned plants directly underneath the reflectors in a circular pattern.

They Look Alot A Like.????

Hey Munchie, the other night I had to spray my plants with the lights on and this evening I noticed a few of the upper leaves on several of the plants look like your spots. We looked under the microscope and they're just burn dots. Yours are probably the same thing. Don't mist for the next few days and keep a close eye on them. I'm going to do the same with mine. Good luck and let me know how it turns out.

Yea I'm real bad about misting some 3 times a day when the lights are on too and yes there only at the top.
No more of that from here out, will see if they improve.
Thanks for the help

i think thats your problem... try misting just before lights out if possible.

I believe the invention of optics was first discovered when observing a water droplet on a leaf showing a magnification from the droplet of water.

The droplet in the sun would cause burning, I will stop it for sure and only mist at the end of the light cycle.

Thanks

I think its like the other members said. Its from the misting. You just have to leave the lights off and let the foliage dry before you turn them back on. Its a lot worst when you burn your buds from doing the same thing! Make sure you let your foliage dry before closing the room too! You dont want any chance of mold!

hot spot burns caused by water droplets on the foliage - happens
