<span class="link_user">@Schnabeldino</span>, yea actually i used coco because it was recommeneded by Autopot. It is actually a substrat that is hard to maintain. Living soil is an substrat which shouldnt need fertilizer if prepared right.So i can only use water in my reservoir. Therefore i will try living soil next grow.
<span class="link_user">@Techii</span>, Okay, maybe that's the problem, you're using Coco/Perlite, these media have no nutrients. Maybe you don't have enough nutrients at the beginning... There is extra fertilizer from Advanced Nutrients for Coco Soil. Maybe u have the wrong fertilizer. Check it out my friend.

Hey, I use the fertilization schedule as directed by advanced nutrients. Maybe you are right , i will reduce it little bit. Im using a coco perlit 50/50 mix. I cant really tell you the PPFD. But the lamp is currently running at 200W. The Autopot system is a bottom feeding system.
