DWC - Critical Autoflower

Do you know the meme with the dog in a chemistry lab and it says : I have no idea what i'm doing. That's how DWC felt for the first few weeks. I reached week 8 now and the plant just explodes with growth even though i'm using Bio Bizz fertilizer. But here we are with a pretty decent sized plant, lets see what happens in the next few weeks but she is healthy and grows very fast now. The solution is only at around 850 ppm, normally at this stage it should be higher, I will try to get it up a bit during the next weeks.
