Is that coco? Whatever it is that plant needs feeding. The medium could use a load of perlite.
Can you recommend an all-in-one for now? I have this but I'm guessing I need to use this laterNeed to feed. Water when thirsty not based on days... they look depleted of nutrients.
I'd give then 1/4 strength vellum and grow nutrients. Autos can be sensitive to nutes, but need some to yield...
