Hi people. This is my first post so bear with me. The problem I'm having is during week 7 I noticed the bottom buds of my plants is changing to the pictures I’ve posted. It looks like what ever it is, it’s working its way up to the colas. I also posted one picture of what the good bud is and should be looking like. The whole room is doing this. Has anyone experience this? My ph is always from 5.8 to 6.2 using 6” rockwool cubes. For nutes I use general hydro purple and pink. Also cal mag, bigbud or overdrive, sweet raw, pk booster, pro sil.
