Yeah,
Yeah, using mystery soil is always a gamble. It's hard to pinpoint the problem when you don't know what's in your grow medium. I think you should definitely give them some veg nutrients! They are extremely deficient of something, or multiple things! Give them some MaxSea all purpose at a low dose! Let that soil dry out real well before you transplant or it's going to crumble on you. I doubt those roots are big enough to hold all the soil together. I hate to sound grim, but whatever that problem is it's pretty advanced. Ocean Forest has a lot of nutrients in it already, so just transplant and hope for healthy new growth. Those leaves will never recover from whatever is going on so don't stress about them. Just focus on healthy new growth. And seriously, let them dry out before you water. Every other day on a plant that size with stunted growth and issues is not helping. Good luck bro!
