Try to give as much info as possible. It could be nute burn, heat stress, bugs etc. Try going with the most obvious things and rule them out one at a time. It doesn't look that bad so I wouldn't worry too much. The burn spots aside, your plants look pretty healthy. Good luck my friend.These six girls are growing on my bedroom terrace just out of site from my neighbors.
What is this and how do I stop it?
It's spreading
Thanks
Heat stress?Nope. does not look like bugs.
Yeah I would lean more to a defiency rather than heat or bugs.Might be calcium deficiency.
