This are still growing well. I wasn't looking close at the buds, but looking back now I should have realized these were close to harvest. I have instead starting to increase the nutrient level instead of starting to flush the water. No issues observed. The Sour stomper is very very very smelly while the mystery seed has no weed smell at all.
The Sour stomper ended up much more chaotic than I planned. Not much I can do to train it differently as I do not want to lose yield or stress the plant by cutting it. The mystery seed looks exactly how I wanted. Has a nice main stem and two side stems. It feels purposeful while the sour stomper is all crazy, haha. Both are still fun to see how they have developed.
