Having some trouble with my plants . I noticed one of my plants leafs at the top tips turning yellow and bottom leafs started getting brown spots.

Right

So maybe more info on your grow would help, don't u think, besides just a pic

But you do you boo

Hey, Are you using Well Water or City water with chlorine in it ? I see some heat stress and Possible Cal Mag def. be careful not to over water.

Good Luck. PS more info can always help others help you. Like Humidity, Nutes, Medium, Lights, just a heads up, You may get much more help.

The brown/black/purple spots on the leaf are caused by a Phosphorus deficiency.

I don't see any Calcium or Magnesium problems.

Need to know your medium, nutrients you're using and how much, as well as the pH of the nutrient solution you're giving your plants.
