Do you know what strain? That's 2 months they should be nearing finish but look like they have a ways. Your pistil( little white hair things on buds ) are still pure white. No red or brown at all. Do you have any nutes? I'd water real good n give them a low dose of bloom nute. Second 2 numbers. Keep lower than 10. So if you have a strong nute dilute it to where the math adds up to less than 10 on phosphorus. Ex. beastie bloomz is a 0-50-30 npk ratio. Dilute that by putting 5x directed amount the water on it. That would make it a 0-10-6 Mix nutes by the gallons. Easier for small garden.
