I see classic signs of overwatering...Do you spray your plants? It's really unnecessary. Just water the roots.

They look healthy though. Very healthy actually. But I would say stop spraying them and just keep waiting.

Your strain might take longer to flower than you wish to wait...By the looks of those buds you still have at least 2-3 WEEKS left on em.

Only other problem might be improper light temperature. What kind of lighting are you using? What is its Kelvin rating?
