My plants are 4 weeks into flowering,and are well over 7 ft tall. My problem is: I'm seeing yellowing of many leaves and what seems to me to be slow bud growth. There are many small buds everywhere, but doesn't seem like they're getting any bigger. I have them in ground. Can they be nutrient locked up, and if so what's best way to get them healthy again? I flushed them really heavy 2 days ago with plain water, is there anything more I should do? We have been getting a lot of rain here this year. 15 out of last 18 days we've had rain. Humidity here is like 87% temp mid 90's. Could this just be heat issues?
