So I've recently learned I've been underfeeding my plants, so far in this stage of flower I've barely been able to manage 600 ppm in half a week... I'm using advanced nutrients ph perfect , 20 ml of each micro, grow and bloom... she has minimal nute burn.... but at this stage does she look like she's growing the normal route?
Looks good to me. I don't understand "barely been able to manage 600ppm in half a week" Either way that plant dosen't look underfed from my house.
You are not underfeeding. I grow hydro autos, and it's rare that I have a strain that can tolerate 600 ppm (EC=1.2). It appears that you have a solid grow medium, so my numbers might not apply, other that to say that autos need less food. Most of mine are a bit under 500 ppm right now, and will want less as harvest approaches.
