But you have glasses on Peteey!

Now don't trust my old eyes but from what I ca see it's only 1 leaf and possibly the leaf next to it. How do you water have you accidentally brushed the leaf as you've been watering so you get whats called a splash burn. I may be wrong and there are much more knowledgeable growers on here than me who I'm sure will have a peek at some point.
The rest of the plant looks healthy enough nicely grown![]()
Your plants will droop right before lights out or during. They know when its their down time and plants droop when the are "sleeping" Check your ph going in and the runoff to see where you are at with PH! PH dropping off in your medium would be where I look first.![]()
you are fine bro, might want to look around for some dolomite lime and put a TBSP on top. I usually go with 1 TBSP per gallon of mix, but you wont need that much! Great looking plant and you are doing it right! Don't freak, you are in good shape. Have any cal/mag on hand?
I run led and led sucks th ecal/mag right out of the plant by week 3, so for me, yes. You can use epsome salt and molasses for organic cal/mag and the sugar from the molasses is good for the microbes in the soil. Use only blackstrap molasses if you are going to use it. 1 tbsp per gallon on the days you only give her water.
no problem at all brother! Happy to help! 1/2 tsp per every 2 gallons of water on the epsome salt and 1 TBSP per gallon of molasses every other watering. I usually alternate, feed, then hit em with the epsome salt and molasses with plain water the next watering. Be careful, on the epsome salt, less is the way to go, it can build up the salts pretty quick if you over do it.
