im having few problems with brown bits on leafs never seen it before on my plants

some the leafs are twisted top leafs are going pale green and brown spots anyone know whats up?

growing in dwc ph fine not sure about ppms i normally just guess as what to add and normally works out ok

temp about 32 so bit high

anyone know what the brown nbits are on some new growth and old near it

oh yeah lights are 300w cfl untill flower

Did you by chance splash some nutes on the leaves?

nooooo i did mist them a few times tho and they do leak water


thanks for your reply

Looks like a burn to me. Most likely some water remained on the leaf(s) and the light burned them. If it's not spreading, I would not worry too much. Just watch the misting, or mist when the lights are off.
