You need to choose hydro or soil. If you mix them you end up like this and we really can't help you. At this point you need to follow @Tangerine_ 's advice andI water when top of soil get dry
Treat it like semi-hydro, but most newbies can't do that. Fuck I've been growing for a minute and I couldn't do that. I wish you the very best of luck on finishing this. Maybe someone else can help you walk this tightrope. As for me I'd move to just water and pray.Treat it like semi hydro but feed lightly. You may be able to limp these to the finish line.
and get those walls covered up with some panda film.
