Please explain me how to recognize nute burn?

[maimunji]

I can see brown leaf tips in every great buds in every leaf here in icmag and other forum. What actualy mean this? Is this growers overfeed plants or what? It is normal for plants to have brown tips in flower? What is difference between this brown burn tips and overfeed?

Brown leaf tips are a way the plant is saying it's over fertilized. Use just water and watch to see if less brown tips occur.

Plants need lots of N during vegging, but it's easy to overdo it. Added too much? Flush the soil with plain water. Soluble nitrogen (especially nitrate) is the form that's the most quickly available to the roots, while insoluble N (like urea) first needs to be broken down by microbes in the soil before the roots can absorb it. Avoid excessive ammonium nitrogen, which can interfere with other nutrients. Too much N delays flowering. Plants should be allowed to become N-deficient late in flowering for best flavor.

Nitrogen is a key Element in the production of Amino Acids, which are the building block of Proteins. Many plant hormones contain Nitrogen as well as Chlorophyll, DNA and RNA (Genetic materials), and a myriad of enzymes that help control and regulate growth. Nitrogen is the most mobile element.

Plants suffering from this deficiency are distinct in their pattern of yellowing. Yellowing starts on the older leaves and progresses upward, leaving the top parts of the plant green.
Notice that the large fan leaves are yellowing and turning purple-ish. from the bottom up.

Ok, but I can see burn tips in every decent bud photo in Internet. Looks like every grower overfeed

It's a very common mindset to push the plant as far as you can. Dialing in a strain typically amounts to raising EC until the tips burn, then dialing it back a few points. More common with conventional feeds but you see a lot of burnt tips with the straight organic growers as well.

burnt tips i feel is normally excess calcium from all the feedings.

its pretty damn common to have the little burnt tip look, but if you can avoid it now that just means you have your strain dialed!

You won't see burnt tips on the best organic growers buds. Sexiest looking plants around. Chem buds suck.

Ok, but after burn tips what is progression burn teeth, burn spots or? And what is difference between nute burn and heat stress? They look simular in pics.

Yes, you are correct. Heat stress is similarly looking. So, see if you can get more air flow in your space., raise the lights, cut down on nutes.

Chemical applications, foliar or water feeding....tastes nasty (not to mention what you do to your lungs). Definitely water well the last few weeks to leach out chemicals. As Scappy-doo said....organic is the way to go, to grow.

However, some like the nutrient boost of synthetics...the choice is yours.

Too, as in pic provided...yellow leaves curled UNDER is a major sign of over fertilization, not nutrient deficiency.

Below, a chart showing common problems...even though it's hydro focused, the same problems can present in soil. Going with good aerated soil, organic, there is no need to supplement. To each their own. there's umpteen ways to grow.

Identifying problems and resolving quickly is the key.
