And the leaves are curled which is a sign of stress. When was the last time you watered them? What's the temp/humidity in your grow room?

 

They look like they're in soil so I'd recommend getting Manutec Bloom Booster (Bunnings or Big W).

Any type of nutrients low in nitrogen will do. Have a look in your local hydro store. There will be plenty to choose from.

I would say that while the plant was in veg, there was enough nitrogen in the soil to keep it happy. But when it went to flower, its nutritional requirements changed, and the soil didnt have the neuts it needed for the flower phase (phosphorus? potassium?)

 

Just a thought.

personally?

I'm a noob so I could be totally wrong - a lil P+K A+B, and possibly some shooting powder.

And some more water.
