Why are these dwarfing? Nutrient burn?

Hey growers and stoners alike.

Need some help neutralising this problem.
I was told to feed these plants 2 times a day so I spread the nutrients out with the recommended nutrients.
I'm crowing in 20% perlite and 80% coco (approx.)

I been feeding them plagron:

coco a and b
Power roots and pure zym.

Ph at 5.5-5.8
(Havent monitored EC)

These plants are growing big leaves but them stem is not growing at all. How do these stretch?
This is a fucking disaster, feels like I'm losing out ffs.

Growing fast buds stardawg (auto)
I hope someone knows what's going on

Plants look ok to me. Have you looked up the specific genetics or see what other folks are doing with them? Perhaps it's just a short, bushy plant in general...and they look as though they're just starting to flower, so yeah...Not sure I'd be doing much to them. The deformed leaf isn't an issue unless it's all over your plant. Good luck

It looks great man. Depending on genetics. It can double if not triple in height when it goes through flowering stretch.
