LSD-25 not progressingMy LSD-25 is not progressing at all. I don't know what I can do to push-start it, the medium is coco coir and perlite mix and I did buffer with CalMag. Other plants are just fine. Might be the luck of the draw but I'm still being patient with her. Any thoughts on this?5y ago

Thoughts about harvestingHello guys ! This question is about my Purple Queen Auto.
She's a little bit over 8 weeks old now (5 weeks into flowering) and I really don't know when to harvest her.
I know about the trichrome method but I only have my eyes to zoom haha
So, when do you think she will be ready?Other. General questions

Hey guys and girls.
My buddy is at her 40th day of life and has gotten into flowering for good (check my diary).
Will she grow taller and thicker or not?
I think I caused nutrient lockout last week and she started flowering earlier than expected. Will that affect my yields?Week 5

Grower's Questions QuestionSo if I correctly understood a comment I read, only those who've signed up for the contest should answer questions? Regardless of relevant experience? Regardless of misinformation? If so, I'll mind my own business. If not, I'll keep trying to help where I have knowledge.Week 6

Flowering taking so muchExactly one month ago I shifted the light cycle to 11/13 and flowering is taking so much time in my plants. Could be high temperatures? Could be related to the fact that the light was on during the night? I have recently changed to 12/12 and the lamp is on during the day. Thanks!Week 11
