Hey doob so I've had the exact same problem, premature pistil discoloration and I've heard several possible factors, humidity(or vpd)., high temperatures, and various nutrient problems like excessive phosphorus too early in flowering stage or in the vegetative stage. The podcast i listen to kis organics cannabis cultivation and science podcast had a big cultivator mention that broad/russet mites can also be a very big contributor to this...however they are sort of hard to spot and are often mistaken for overwatering, deficiencies and heat.
I've kind of just ended up watching the plant closely for excessive damage and taking it easy on the nutrients. I think you'll make it to harvest just fine but its always nice to try and find the problem.
Happy growing. ✌️

Hi there doobsmog23, you're right, pistils turning brown too early is not excellent. the early oxidization of pistils is a sign of phosphorous excess. So you want to flush if you can and reduce the P before other more serious symptoms appear. To improve pistil health specifically, well nothing much you can do except to keep the whole plant healthy and tuned in correctly. Sorry for the tough answer but it's the truth at least ! hope this helps ! 🚀

3weeks in flower, can i cut the little buds ?Hello ! i heard that cutting the buds that don't get enough lights will make the plant prioritize the higher buds. Should i do it for this plant ?
I have been cutting 1, 2 fan leaves every 2 days for the light access for buds. Thank you for ur help !

Defoliation for better ventilation?Should I defoliate/prune to ensure better ventilation? I am going to flip the plant soon. It is quite bushy with big leaves and sometimes it is difficult to water it as there are a lot of leaves down there.
And when is it better to put the net? Before of after the flip?

When to flush and harvest and should I defoliate again?When to flush and harvest? I think I am close but my gut tells me to keep it on the current nutrients and feeding schedule for another week or 2 and then flush but also don't want to leave it too long.. My stash is all but empty. Also, should I defoliate again?

Defoliation AutoflowerHey fellow growers,
How should I approach defoliation with autoflowers during flowering? I'm thinking of removing lower leaves, especially near the soil. I prefer to be cautious to avoid mistakes. Reddit wasn't helpful as it seemed too critical. I hope for better insights here.

Removing of Big Leafs in Flower Phase ????Does it make sense to remove large leaves in the flowering phase to give the plant the opportunity to send more energy into the flowers or should you leave the larger leaves on because the plant also photosynthesises through them.

First Grow Help And FeedbackHello Grower,
OG Kush Flower Day 24: Lollipopped and defoliated 10 days ago. Can/should I defoliate again? The buds seem like they could get more light. Also, I noticed some sprinkles on the top leaves—could this be from too much P/K? Any tips and general feedback are welcome!

Defoliation (no horizontal room in my tent and a lot of vertical room)This may seem like a dumb question but is cutting these small lower branches off going to promote vertical growth in my plants? I will be doing it later on anyways to eliminate larf but would it be more beneficial now or is it worth to keep to take in light energy for now
