First Ever Grow (RQS Solomatic)

Now quite sure of how she’s looking now is normal or not. She’s got some yellowing in the leaves, which I would guess is maybe nutrient shock of some form? At a guess, maybe a pocket of dry fertilizer from a few weeks ago finally soaked into the soil with watering on Monday (day43), and was too concentrated? Will pose a grow question and try to glean knowledge from the community! I think the buds are looking good, but one is starting to brown up, which I didn’t expect quite so early, but perhaps that’s also within the realm of normal 🤷‍♂️🏻 Day 48: she dropped a few of the hardest hit leaves, but otherwise doesn't seem much worse for wear and the buds seem to be filling in pretty well. Per feedback to my grow question, I gave her a half dose of veg stage fertilizer with watering, and will keep an eye out for greening back up a bit. More pistils are browning up, so I don't know how many more weeks she will need, but will just have to watch and learn!
