answered grow question 6y ago
Hi Mate, It seems to me an initial K deficiency. Also I have noticed the edges of the serrated leaves begin to curl up as heat/overwater stress. I think that only little corrections are needed, she is quite healthy. IMO 🤞

All my plants are infested of thrips ! I didn't notice before, beginner mistake ! I can see the thrips under the leaves, even close to the buds. I'm about to harvest 1 plant very soon and the others in the coming weeks, can I harvest anyway or I have to get rid of them before ?

Can anyone tell me what's going on with my plant? Yellowing leaves with brown spots on them. I've never had this issue before so I'm at a loss. I've tried a few things but want an opinion from someone who may help. Thank you.

Cut off leaves for better bud development?
I saw some diaries where plants have nearly no leaves and produce a nice amount of good looking buds. Is it recommended to cut of most of the leaves at the end of flowering, that the energie goes into bud development?

Need help diagnosing leaf loss issues with the G13 Haze strain (problem has been over 5 weeks now). The one in the smallest pot (7L) has lost a majority of its leaves. The leaves start yellowing and turning brown then crispy. They have white speckles on them like salt.

What’s that? Pests?
How can I get rid of this? I’ve spotted these marks on some of her leaves. Should I remove infected leaves or something else?

First problem, need help!
Calcium deficiency? I'm a newbie, but this is my first major issue and I'm thinking it's some sort of nutrient issue.

Can´t figure out what´s this.
So, it appeared today after the night hours. She´s and auto amnesia, 4-5th week, GHF BioGrow mixed in the substrate. I can´t figure out what is this, does someone know? I think it might be related to ph or overfeed? Thanks!

Which deficiency?
So I've asked before if it was a magnesium deficiency on the GC and got confirmation based on the early pic, but now I'm starting to wonder if it is? Buds don't seem to fatten up either. Maybe calcium or potassium? Lights too strong? Overfed? Shouldn't have given Vega just flower

Orange dots
Too much stress and light maybe? Should I use a little bit more of CalMag for this lady? This is a Mexican Airlines on day 12, topped. I know these are really small dots, but I like to prevent.

Slimy oily film on leaf
Noticed a pool of slimy oily film on the top fan leaf. Pic taken after I touched it and smudged it. Doesn’t have any smell and not sticky. Nothing dropped on it. After wiping it never came back. What could it be?
