Wedding Glue 2021 - SKYLAB

Trouble in paradise this week. Came out to find leaves with brown spots, yellowing. I think it's Cal/Mag and maybe Nitrogen deficiencies but more generally I think I've got to feed these plants more (every watering in flower- that's my guess) now that I have double the lights and I'm running them 24/7. If it gets any worse, I may flush, or add some liquid kelp fertilizer. Whatever works, it still raises questions about what was lacking about my feeding schedule, why my plants were usually pretty short, and under-performing. I've got a couple of Gorilla Cookies and a Blue Dream (all autos) showing the same yellowing and crispy-ness later in flower. In 2 weeks I'm stepping away from liquid nutes completely. I'm going with Down To Earth's line, amending the soil with Worm Castings, Perlite, etc. and I'm expecting to top dress maybe 3 times. If anyone has any advice about the brown spots, and yellowing please advise! I upped the Cal/Mag and added a bloom booster with a good amount of P and K right away. I'll try feeding her every water now (at the end of Week 7/start of Week 8), plus Bloom Booster. Really hope I'm not slowing her down, she was growing so well up to this week.
