Possible nutrient burn ?

Seldom_Seenstarted grow question 3y ago

I’m pretty sure this is nutrient burn but it’s weird because I’ve only given a tiny dose of nutrients so far. Less than a quarter of recommended dose and probably less than I’ve ever given an auto before. What do people think ? Nutrient burn ?

I had the same thing happen in DWC, personally it didn't have any impact on growth and it didn't continue developing, but I researched and came to the conclusion that it could be 2 things: 1_ Excess light, it could be light burn. 2_ Something related to calmag, which coincidentally is often linked to excess nitrogen, meaning if there's excess nitrogen, the plant won't properly absorb calmag, which could show a deficiency due to nitrogen excess. If the plant's leaves are very dark, I recommend lowering the nitrogen dose in the fertilizers that contain it a bit. If the leaves are a normal color (as I can see in the photos, although I don't know what color of light they are under), you could add calmag in low doses to see what happens, although if it's your only symptom I don't consider it a problem. Anyway, I raised my lights a bit, added some calmag, and the new growth was normal without issues, it's not something to worry about, cheers!

To make sure that the soil does contains the right amount of nutrients and is within the right pH range you can water the pot till you've got 20% from the pot volume as runoff. Measure the runoff and check if the runoff doesn't contain a too high EC or pH value. It is better to give nutrients every other watering to prevent build up salts and nutrients. And water twice a month till 20% runoff and measure.

Nutrient burn turns the tips orange buddy :) This would be the start of some kind of defiancey i would say calmag by looking at it but it also could be nitrogen you do know you can get burnt tips by not enough feed too its the same symptom :) Best of luck buddy I'm sure a good feed will sort it right out.

With such a low dose, I don't think so.. and the only thing other than what i think it is, Is excess N, but your leafs aren't a deep green. That and what you're giving, I give my seedling 4x that of alga grow. It looks to me as it's from overwatering. And your roots are finding it hard to breath. You need to pull back on the feeds. Or partly feed 1 side. As a young plant can find it hard to fully dry out her sub, and roots need to breath. And when they can't that is a symptom. That you overfed maybe once or twice, not saying its a common problem, but is results of drowning roots..
