What's wrong with lemon cheese? Is it overfed...

Hey there , this looks like pH fluctuations to me , you can tell from the " splotchy burning ", soiless is challenging , can't tell what nutes you're using for some reason but seems you're doing well already ... You're looking to add one of each veg NPK , calmagmicro , and a chelation agent like flawless finish what you're already using. So if out have these nutrients you should also get some pH up and down , getting pH right is the toughest part of growing , you're looking for 5.9/6 .... I use strips because they're cheap and you don't need to calibrate the things ... Fix this and the problem will stop spreading but the affected leafs won't recover . Hope this helps ! 🚀
