Droopy leafs getting worse. What am I missing?

could be a few things but lets get the watering habits sqared away, first.. who knows what clears up from that. i'd suggest more perlite next time.. approaching 50%. makes overwatering virtually impossible. (30% with coco, not 50) you don't pick teh volume... the size of the pot and when you irrigate determines the volume needed. you can only learn this retroactively or by doing things the same way each time as far as soil components. Water until you are certain teh entire pot gets wet. Recurring dry pockets will eventually cause problems. Now, you can dial this in to waste the least amount of water and reduce any runoff to near zero. that way you don't waste what nutrients come pre-loaded into the soil. i would reduce your current feeding regimen.. either less frequent or lower concentration or combo of the two.. .you can always ramp back up. you'll learn more on the next run when you dial it down a bit and see how the plant reacts to that from a point before problems occur. keep dialing it in better the next time. Watch for any nosedive in leaves if it starts to pale too much then amp it back up and feel more confident it was more about overwatering than nutrient-related, but i would expect some of that curling is too high nutes in substrate. allow the substrate to dry top 1" before re-irrigating or fertilizing... depending on concentration of fertilizer you may need it ever other or every third irrigation.. kinda depends on your personal choices with concentration... more frequent and lower concentrations fed 'on demand' will probably have better results but also reuire more effort from you. but, you go that route you might as well switch to soilless. with soil it's always a guessing game. stick to same products and you can learn how to amp up and supplement whatis lost from soil over time properly to avoid any issues... eventually you'll find a path for a healthy seed to harvest run.
