I've perused the thread and come to the same conclusion, overwatering and perhaps underfeeding. Overwatering prevents nutrient uptake so the plants look deficient. A good way to figure out watering in soil is to fill up an extra pot with the same exact media, and just leave it dry, then lift your pots and compare to the dry pot. Overwatering is the #1 issue for new growers. You want soil to dry out between feeds/waterings, now if you are interested in Coco, it's a bit different. Your leaves will not recover, but you have enough leaves with chlorophyll left to get your plants past the finish line if you fix your issues. Next grow, I'd switch to Jack's part A&B, OR to make mixing even simpler, go with Maxibloom (you can run it all the way through from Veg, or get both maxibloom and gro) or Megacrop 1 part. The reason you should check out these particular nutrients is 2-fold, one, they are complete formulas with plenty of Calcium and magnesium in them, 2, they test out either low in heavy metal content, or totally free of heavy metals (in the case of Maxibloom.) Then you just need a decent PH and TDS/EC meter. You'll find that you can grow outstanding buds even with a fairly low ppm of 600 during bloom. Ph depends on soil or Coco/promix. Next round, shoot for perfect beautiful green leaves all the way through, trying not to even burn the tips-if you succeed in that, with one of those nutrients, the buds will follow. Be sure to check back before you harvest with pics because the next big issue new growers (and many long time growers) have is harvesting too early. Forget Covid, early harvest is the REAL PANDEMIC, but also, Covid is too....
