Hi everyone, first grow. I was wondering why my front left plant (sour giesel) seems to have some off coloration. I was wondering if anyone could help identify it before I flip to flower. Based on the charts online I wanna say sulfur deficiency but I’m not totally sure. I’ve been using craft blend, buildaflower, rootwise mycrobe complete and some local worm castings. I needed to order some more craft blend anyway so I picked up some big 6 as well in hopes it helps.

The back and right one are G-1000 (T-1000 x GG4) and and front left is Sour Giesel (Giesel x sour diesel) Any suggestions or advice? I know the far right plant is pretty runty, but I was planning to flip within the next week or so. Should I wait longer?
