Hi all,
I realize I should be able to find the answer to this question online, but I haven't been able to.. appreciate any insight!
I'm not sure if what I'm seeing is light burn or a nute issue - the tips of all the leaves have turned brown. The rest of each leaf is fine. Any thoughts?
Long story short - the pH in my DWC is low (trying to fix it), and my led light had been too low for a while (it's now 18" away from the top)
--(pH)--
So, I'm growing in DWC, and my water has been too low of a pH lately. I was using a pH meter that has been giving incorrect readings (pH meter had said 5.5 when pH drops come out to <4). I started using pH up, but I'm still working on correcting pH.
--(light)--
My led light was like 12" away from the top for a while, and it definitely bleached a few tops (the very tip turned white). For a while, I figured the brown tips on the leaves was from the light, but this browning is happening on all the leaves equally.
