I’m not at home at the moment and will not be back until tomorrow, This is my first grow and the only plant that has the problem. I think it’s nitrogen toxicity, am I correct? (I could only get 1 photo and the led is on, sorry about the quality)

Be better to tell once you get back and have photos without the light on.

My friend took it with the light on, told him not to but still did. I’ll post another few photos tomorrow

Could be low pH in the medium. I have been seeing a lot of this lately. If the leaves end up with burn patterns that look like stripes then thats the likely cause (low pH). The medium pH is not always in line with the feed pH.

BTW - is that plant an auto? looks like it has some ruderalis genes, definitely different.

If I test the run off and it’s low, how would I make the ph what it needs to be?

Testing runoff will not provide an accurate indication. A good digital soil pH meter (not the cheap analog ones) is required.

The info you seek is here

Burn from lights?? Need input

The only cheap solution that will ballpark things is the chemical soil pH test kits but thats a PITA to get soil from deeper than maybe an inch and I find them hard to read. So I did a run off test on the blue haze and I was hitting 5.2 Jesus. I got it back up to 6.2 for now. I haven’t tested...

and in several other threads that I have shared this in.
