droopyleaves

Hi so this is my first time growing and the bottom leaves are droopy? Can someone please explain why and tell me how to fix it asap I think it might be that those leaves aren’t getting enough light?? Also the tips of my leaves are turning yellow and curled downwards (im struggling for real!!)

My leaves on my plants are drooping yet still green. They've been doing it for a few days now. Don't believe it's a watering thing since I wait till they dry out and then water till about 20% run off. I mix perilite with basic ocean forest fox farms soil. Should I be mixing something else with...
