Is this nutrition burn?

[Ferboldt]

Hi everyone,

Here I have an Lemon OG Haze Aut. Fem from Nirvana.

She is 5 weeks from seed in AeroGarden 1gallon with 45w LED lights.

I was feeding her with the AeroGarden standard liquid nutritions. After starting with Flora Series;

Micro 7.5ml
Gro 7.5ml
Bloom 7.5ml

Got marks on leaf. What is it?

That's your PH. Try adjusting the PH to proper levels (Hydro correct? 5.5-6 should be good. I'm a soil man myself but....)and waiting a few days to a week to see if it clears up. by "clearing up" I mean the new growth wont be effected. Or anywhere else. Chances are where it was "burned" it will never clear up, so you can either cut the leafs back, or pluck em. (I like cutting em back ) Hope this helps

I think it's nitrogen toxicity and the light heat helps the leaf burn flush your plant with lot's of clean ph 6.5 water.

See the claw there too. Not sure if it's correlated. I had brown spots and the claw so I assumed nitRogen toxicity as well. Fed regular water for next feeding and new growth is good.
