hi, just a bit of nitrogen in excess, but nothing to worry about. plant its storing it on the bottom leaves "just in case". the claw its slight so i would leave all like this, but if you want to fix it just give them less nutrients. cheers

Week 5 leaves beginning to curl and claw slightly Up until week 5 everything has been going smoothly but at day 31 I can see some leaves starting to curl and claw. This is 2 days after minor defoliation. I’m not sure what could be causing it, I turned the fan down a bit so it shouldn’t be airflow but maybe too little nitrogen?

I may have over watered or it could be nutrient lockout. I only feed them every 10days to 2wks. I was switching them over from 1 fert to bloom fert by mixing 1 tsp of ea into 1 gal water but I did it 2x in a row. BEST WAY TO FIX THIS ???

Is this plant male? It was at the back and my seeds are feminised so I never bothered to look .Did I let a male ruin my grow? 🙈 I have removed it although it would already be too late it's in my kitchen lol. All the other plants are showing lots of hair and buds this one is growing very differently. Did I get stung with bad seeds?
