Two questions: first, your light appears to be 840 watts. How high is your output on the light (percentage)? Secondly, did this appear at the bottom of the plant first and work its way up, or are you seeing this only at the top?

Did it start showing signs on the top, middle, or bottom of the plant?

middle of the plant and its not as bad at the bottom but still showing same signs

Nute burn usually starts at the bottom of the plant and goes upwards so if it were me I would raise the light a bit or turn down the intensity.

What nutes are you using and how much?

dutchfest bloom nutrients i just add equal parts to a 30 litre container till the ec is at 1. 3 cap fulls of each

I’m not familiar with that nutrient line but they advertise as being specially formulated for HID lighting versus LEDs. I have no idea how much of a difference that actually makes but hang in there and I’m sure someone will chime in who grows hydro who may be knowledgeable in the line you’re growing with.

Did you pH your water before or after adding the nutrients?
