Hey man good looking plants, nice and healthy. Liking how your droopy plant is pulling threw. You must have a green thumb
. Finally got those branches coming strong. Take a look at my updates on my grow to see how the flowering happened. Took her 11 days to finally show a small pistil on one of the branch joints. I am 18 days in and have bud forming and only had 1 plant as you know so I got pretty lucky. In your case your going to be guaranteed at least 1 female but hopefully a full crops worth mate
.
For your temp and humidity it is best to have them lower than what they where on veg. Around 24'c (75' F) for temperature and 40' to 45' for humidity. I have been having mine on 35' because of a dry fall coming my way and not having a humidifier and the plant doesnt seem to mind that much. One tip I have is natural molasses from any grocery store for your plant, give it every watering at max of 2 tbsp per gallon. It will make your buds taste better and is a good natural fertilizer with your main flowering fert.
Happy growing and good luck!
