So, 4 plants. judging by the leaves, there is either a nutrient deficiency or lack of nutrients. This week, I will be defoliation, I think the final one, and onward to the harvest!
I will listen to all advice, with pleasure π
You have to low down humidity to 50% at least because it could cause bud rot with time and thats something you dont want to see ever. Everythings looking good,healthy and beautiful plants. Last bigger defoliation make in 3rd week of flowering to make space for airflow under between branches which is very important in blooming.
Take care man and good luck. If you need any advice be free to message me. Regards broπππ»πΆβπ«οΈ
It's all up to you on when to switch to flower. π I usually make the decision when I plan the grow based on available time frame, strain, and desired yield.
