Clementine Rhythm Bagseed

Pretty sure that Clem had been developing a nutrient deficiency due to lockout over the course of the last few weeks. Still not totally sure which nutrient(s) - based on some articles it looks like mg deficiency or a few combined? Some of the older leaves started to show burnt tips/brown spots and the plant was looking a little yellow. I flushed and then watered with half strength nutes and towards the end of the week it started to look a lot better. Last watering the runoff came in at 850ppm. Going to keep it there. Last week in Veg so I’m hoping Clem isn’t too stressed out. Defoliated a bit more and did a little LST to prep for flowering.
