First Grow - Barney's Wedding Cake Auto

This was a tough week. Last week I noticed spider mites, so I did three rounds of Trifecta which appears to have done the job. Then I started noticing yellowing on the lower leaves, I thought I had a cal-mag deficiency, but I think I had nutrient lockout. My run off was 3500ppm so I did a 2 gallon flush to get it around 1000. The plant perked back up over night. I gave it a very small dose of tiger bloom since I probably flushed out all of my Gaia Green bloom. My Colas look were looking really long, but they're starting to fill in now.. fingers crossed. Every week I seem to mess something up, but this plant is still bouncing back. I hope I can get it over the finish line with an okay yield 😀 Lesson learned for the next grow, start feeding a week earlier. I also top dressed with some Langbeinite to help fill out the buds. I've been reading the importance of magnesium and potassium in flower and that calcium isn't needed as much. Learning. I think I finally have my lights adjusted, I'm running around 650 par 20/4 giving me a DLI of around 45. I've been defoliating some of the bad leaves, I've read it's not really good to do this, but I can't look at the half dead leaves anymore :)
