Plants were fed and looked better after 1 day (yellowing was gone) but they stopped growing --> I think they are nutrient burning. I have drained out the nutrient solution add added just neutral pH water to bring the TDS back down to 50 from the 140 reported on this week.
Sorry for lack of relevant pictures as it is the holiday season and I'm too busy to take them and spend as much time in my garden as I would like too ;-).
If I can give you some advice, the plant may or may not look like that when it's finished. Even the same strains don't show the same genes. I had high expectations that my dark devil would be purple and black buds; one is, one is green with purple leaves so :) always just try you best and don't try to compare too mucch :)
