<span class="link_user">@Dadasgrow</span>, thanks bro ;)

<span class="link_user">@krippy</span>, That would help a lot

<span class="link_user">@Stick</span>, even with organics nutrients? I tried one time to read ppm but the measurement was very low... I knew that instruments don&#039;t read them... I&#039;ll try to read the runoff next time...

<span class="link_user">@Stick</span>, thank you so much for the answer, I was thinking about it but wasn&#039;t sure because I gave just half dosages, I&#039;ll do as you suggested next watering ;) Did it... watered with 1ml/litre of enzymes and checked the EC runoff... All plants have a runoff EC between 2.6 and 3.2

Hi <span class="link_user">@krippy</span>! These are the first signs of a Nitrogen toxicity. Considering you&#039;re growing autoflowering strains, you should be very careful about the nutrient intakes, since autos are usually very sensitive to nutrients, they don&#039;t need such doses of fertilizers. In this situation I would flush the medium for 2~4 days with plain pH&#039;d water then see how it goes. Don&#039;t give any nutrient until the new growth have stopped showing burnt tips. Affected leaves won&#039;t recover but the yellowing/burning should not spread if you treat your medium asap. Hope this will help, keep us up-to-date and happy growing :facepunch:
