yan402answered grow question 5d ago Hey bro, it could be a few things:
1000 PPFD might be a bit too much up top, can actually reduce trichome output if it's too intense or warm.
Touching or brushing colas often knocks off frost without noticing.
*mouse got it right if that's the case
*Green_claws has a point no need to turn the pot if you aren't growing at a window and light comes from the top, you could slightly bend the main, up to you.
Tops sometimes mature faster, and the lower buds keep stacking longer.
If the rest looks good and there’s no stress, you’re fine. Maybe ease the light a bit for finish.
