the leaf are cracking???

the leaf are making some crack line. it still soft and the bottom is a bit yellowish. but the crack on the leaf? odd? i got some nutes but im afraid to use the same one since it killed 2 of my plants. i cant afford any more mistakes. any idea what this could be? is there a site that explains everything from water to food, step by step, weeks by weeks ? no offense but it's extremely difficult to keep up with RIU.

How much nutes are you using? And what is your watering schedule? Sounds like they are dried out and may have nute burn?!?

they havent got any nutes. no burns. water everyday but i might be over watering it so i stop since the plant were a lil droppy. didnt water today and the leaf are going back up. i really do need some nutes but i need something VERY simple cuz i dont know how much to put in and i dont want to kill em. i never gave any plant any nutes ever in my life but water. so this is totally new to me.
