Due to the weirdly slow growth I posted a question here to see if anyone could tell me what I was doing wrong and it appears that biobizz was not a good choice of nutes since I'm growing with and perlite coco only.
Unfortunably the damage is done but hey at least I learned something new.
This week I transplanted them into 3l airpots and I have ordered the advanced nutrients sensi coco line in hopes of maybe getting something out of them.
I've also apllied some LST in hopes of having them "stretch" a bit.
