Stickanswered grow question 6 years ago Hi there! 1/ Not if your airflow is good but 30% would be better, in order to avoid rotten buds. 2/ She might be suffering or recovering from a previous mistake. I see your pH is 7, that's not the ideal level, your pH should be in a 6.0-6.5 range. Otherwise this can come from genetics, even if they're all the same strain, you can have different phenotypes. I won't worry too much at this stage but keep a close eye onto her growth. I'll be around, keep us up-to-date and happy growing!
