19-11-2021: Still 4 weeks left... Buds are starting to swell, I think I have to harvest the Runtz a week earlier. Lowered CO2 to 800PPM. Lowered EC to 1.8. Will replace the water by end of the week. 21-11-2021: Some people suggesting I should use PK13/14... But they are not telling why.. Honestly... I have no clue what it could do for me. Already using Green Sensation from Plagron with clearly says..."When you use Green Sensation you don't need a PK fertilizer, enhancer, booster or enzymes!". So I am just continuing as I do. @Hazeydays... Was just rereading your comment but cannot find any grow diary from you :(. Why do you think I should add PK13/14?You said (3 weeks ago) your ladies are in week 7 and 3 times as big as mine. What do you mean by that? Because I think it is quite normal that plants in week 7 flower are bigger then plants I week 1 flower. Do you have a link to your diary? Thanks in advance 23-11-2021: As you can see some buds seem already to be ready for harvest. Very strange, only 56 days of 12/12 now. (I started counting flower on day 27 of 12/12 so only 29 days of real flower. I was told this might be due to adding Green Sensation too early but I would expect all the ladies would suffer from it then. It is just one. Even the lady which is in the same bin doesn't show any signs of amber trichomes. Very Very strange. 24-11-2021: Buds seem to swell very fast now overnight. Looking and smelling great. Today my fans will arrive so from tonight on they will have some windy conditions I hope.
