Nute Burn?

[Ripvanwinkle08]

I unfortunately believe I have Nute burn on one of my plants. This is my first time growing so I want to make sure this is the case. If so what would you recommend to fix it? These are Week 5 From sprouts autoflowers.
Thanks for your help.

Hi mate I’m no expert but I’m thinking it’s a potassium deficiency you have. Sometimes you’ll get something that looks a lot like tip burn with a potassium deficiency, but it goes in further than nutrient burn, and with a potassium deficiency you also see yellowing between the leaf margins (on a few pictures you can start to see this) Sometimes the first symptoms of a cannabis potassium deficiency look a lot like nutrient burn. One difference is the edges of the leaves will also start turning brown, where nutrient burn usually only affects the tips. And unlike with nutrient burn the leaves of a potassium deficiency turn yellow in the margins, especially near the burn edges. Hopefully this helps you out mate

10-4,

Thanks brother,

I’m running FFOF and unfortunately was late feeding(first feed was on Sunday when they showed the potassium deficiency). I went half of what you would feed a 3rd week plant on GH flora series. Then I fed again yesterday with a 2.2.2 per gallon blend plus 3ML Calmag because I thought my first feeding was a little light. So it scared me this morning when I saw the dying leaves lol.

I’ll monitor them closely and shoot any updates if they get worse.
