Nute burn?
Realtree8858
started grow question 2y ago
Is this nute burn or something else? Growing in 5 gallon fabrics pots with soil / the bottom has super soil. Plants are 100 days old.

It is in fact nutrient burn, probably nitrogen. The tell tale sign is the browning of the tips without turning yellow first/around the burned tip.

It's classic nutrient burn 100% Done it before. Looks exactly the same.

my best guess would actually be a potassium deficiency. since the rest of the plant looks healthy. it starts on older leaves and works its way up.

Got some minor leaf burn this week. Only a couple leaves, I thought it might have been from being manhandled during the LST training, but not sure. What do it look like to you?

Athena Blended phosphorus deficiency
I’m having some leaves just on one plant showing phosphorus deficiency and don’t know what to do, any help would be appreciated thanks. I’m on week 5 running 4ml camg, 8ml bloom a, 12ml bloom b, and 10ml PK per gallon feed every 2-3 days. It’s also light greening.

Week 8 - Godzilla Cookies Auto - Feels like they are substantially behind. Thoughts on pest management or feeding schedule tweaks?
Day 54 - Godzilla Cookies Auto. Dealing with whiteflies, soil gnats & a caterpillar (now removed). Currently using neem oil spray & adjusted watering. Plants are full sun/30% shade daily. Avr Temp 20°, Avr Hum 56% How do these look? Are we good, or 'newbie' grow OCD?

Burnt yellow edges autoflower? Too hot?
Some girls show some issue, like burnt yellow edges on the leaves. I have still a little hot hot temperature (over 30C), it's this reason? Or some shortage or surplus? Should I worry? Start of 8th week. 3th week of flower. Thx.

Guess on what this is?
Unsure what this issue might be. PH seems in check going in and out. Getting mainly Fox Farms nutrients - got very weak doses of B-52 and CalMag a week or two ago. The other two plants are fine.

continuing nute burn or deficiency now? biobizz lightmix +organic nutes | runoffs EC 1.8-2.5 | PH 6.3 | DLI 45
cca 10d ago, I found early signs of overfertilization. I reduced nutes, but yellowing continued. After a flush 2d ago, things got worse (now also edges browning). I now suspect potassium deficiency or still nute burn. Next watering is near—should I flush again or feed properly?

Slightly Brown Crinkly Tips
Dose anyone know what could be causing this browning at the leaf edges? It is a bit dry and crinkly to the touch. This is only on the bottom two fan leaves, and only the very tips. All the newer growth looks fine. Nutrient Burn maybe? Should I be worried, or adjust anything?

Nutrient lock out?
Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.

Is the browning caused by nutrient burn or symptoms of something else? I had previously backed off, but want to know if I'm missing something. Most of the stems are red for leaves as well as petrioles. My runoff is around 900 each time @6.1. Only one plant of 2 has this.

I noticed that I had what I thought was nute burn, I had only been feeding half strength canna A/B coco feed so I was confused and just thought that I had a sensitive strain on my hands ( ph5.8 I noticed my lights were on 24hrs! Would this cause the brown leaves?

Nutrient lockout, ph imbalance or nutrient burn?
Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn. The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.
