If you want to post a pic without putting it in your gallery, just scroll down on the screen that you reply on and click on manage attachments, click on one of the browse buttons on the screen that pops up. Find the pic you want on your computer and double click on it. Then click upload on the bottom of the pop up window. RB

Click to expand...

wtf is light burn? You mean a toxic amount of wattage in the grow room? I don't think that is common enough to every be given as a diagnoses. At that amount of light you would be blinded every time you tried to look at your plants while the lights were on.


Just my two cents.

To be honest it looks like a Potassium def. try these links.

Is this a seedling that might be autoflowering into a male? or is it truly a mom?

If its a mom I would leach the soil and start fresh with ph balanced nutrients letting her dry out pretty well before rewatering.
She could be on the toxic side and or too wet like mentioned before.

Are you ph adjusting your nutes and water?
Is the run off after watering/feeding way out of range (most often too low)?
This happens alot and while the plants show deficiency they are really becoming toxic with the nutrients just being locked out.
