Leaves turning brown and drying out.

Hi,

A week ago i noticed little brown dots on the first "real" bottom leaves (not the round ones). Afterwards the damaged leaves dries out. Tried adding mg sulfate solution, but i see no changes. Ph level in soil is around 6.9.
Maybe you can give me some advice? I added two pics - one, with the brown dots; other, where the leave has already dried out.

I thought this was going to be nitrogen def, no idea what that is though.

I'd wait till it's time to water, then run plain water through the soil a couple times, then water with Dynagro Grow at 15/ml per gallon (check the PH before you water) So much easier to just use Dynagro Grow than try to guess deficiencies and correct them individually.

Looks like nute burn.

I have just started using nutes, and the brown dots appeared before i started using them. Can the burns be from the nutes in soil? I used some kind of universal soil. Maybe i should replant my plants in different kind of soil?

Contents of the soil i used - N-150 P-270 K-300 (mg/l) рН 6,0 – 6,5

That soil seems pretty hot. What week did you start feeding nutes what brand and how much? I am now using FFOF and had to adjust my feedings or I get nute burn.

It can`t be from nutes, because i started using them after one of the leaves died. What kind of soil should i use when i replant my plants?

The nutes i used has NPK 10-10-10. A friend of mine was using them in his grow, so when i couldn`t find anything else, i bought this one. But now i`m looking for a website which ships dyna-gro liquid grow 7-9-5 to Europe.

I use Fox Farms Ocean Forest with excellent results.

Yeah, i believe that it`s great, but it`s pretty impossible to get anything from Fox Farms to eastern part of Europe (without paying ~50$ for shipping). I just found a store that ships Bio Bizz All-Mix to my country. I guess it`s the best soil i can get.

Another thing - i have been using the same soil since the beginning (they`re about 1 1/2 month old), but the nute burns appeared only like week ago. Can it be nute burn from soil?

Those first leaves are suppose to die (3 bladed) its normal any leaves above that then you have a problem.

The brown dots are appearing on next level leaves as well.

Agree with the Chi-Town guy, the bottom leaves are supposed to die, and they will look bad as the plant moves all the mobile nutrients to the quickly growing parts of the plants.

I still can`t understand - is it nute burn from soil, mg def or something else. Today flushed all three plants with plain water and if it will progress i`m going to transplant all my plants in different, more natural soil. Added new pic from today, maybe it will help to set a diagnose. View attachment 2407188

In the future, avoid all soils with chemical nutrients, because you never can tell. Always use organic soil or soilless mix.

Thanks for advice. So i should transplant my plants to more neutral soil and see how they behave there? Sorry for all the moronic questions, i`m first time grower and everything was going smooth until now, so i`m kind of confused at the moment.
