So this week plant growth slowed for sure, not sure why. Maybe a p/k deficiency? I've been PHing properly between 5.8 and 6.2. PPM levels for intake are around 600. Multiple people on discord told me not to worry about measuring the runoff PPM, which I thought was strange. I still measure it but it is becoming more and more of a hassle. I'll make a nice post next week. No sign of flowering thank goodness, I think all the crappy LST has really stunted them. I took the stakes out of the coco, that also might be an issue since they go so far into the soil they might be hurting the roots. Then I saw the canopy rising again so I tied them down again. I think I'll try manifolding or supercropping next time around. The C99 x blueberry fast has the same issues as the other ones, making me think it's something lacking in my nutrients. I put Bio grow into the mix again thinking it needs nitrogen. The leaves seem to do this after they pop out nice and formed then start to brown at the tips and eventually see what you see. I'm thinking it's because I'm not using activera or fish mix, at least I hope so. I figured I needed some dry amendments so I bought some Down-to-Earth Bio-Live that I literally put in a salt shaker and I will be giving the top soil a some shakes as to not burn my plants more then they already are.
