What gave this? Light excess or nutrient burn or lack?
I had this symptom from the beginning, stable, I didn't worry too much. What could be the reason? How to avoid this in the next grow. I mean, it's minor, but might be better to attend and unleash a better result. I have this on all buds, on canopy it comes with curly leaves.

Defoliation late in flower on Auto's
I like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!

First Grow Help And Feedback
Hello 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!

Yellow leaves black tips
What’s happening with this plant? After watering all my plants 2 days ago, one of them has been quite droopy and developed these yellow areas with dark tips. Is it a watering issue / heat / deficiency? Thank you

Slight yellowing/burnt tips and spots
Slight yellowing of leaf tips. Very little and plants are looking generally healthy. They are in bio bizz all mix! And theyve had one feed of fish mix and 2 of molasses I’m watering with rain water. Not too worried but would be good to know what is causing it

Am I correct that the brown tips are nutrient burn? Should I alternate giving nutrients and water? Say, nutrients on day 1, then water 4 days later, then nutrients 4 days after that, then water, etc.?

Super Urgent, first time grower, batch might go to heaven - plants look beaten up, I suspect light stress or overwatering
