Ok, son technically flowering start around 2-3 days before you actually see pistils. It's hard to figure if you've just set off, but with time you'll see how plants starts forming kinda cup that later pistils start springing from. But yeah it happens more or less when you see these white hairs growing.
When you flip, plants starts adapting to new photoperiod and she stretches 2-3 weeks on average. OG will stretch a fair bit and it's already a rather lanky strain, so you want to get your arms around it and make sure you make these stems and branches strong with LITTLE NITROGEN, cause NITROGEN contributes to bigger water accumulation, which weakens the system if used too often. I recommend starting her on Ca/Mg supplement instead, and leave bat guano out for now.
Alright cool. My next watering will be a cal/mag treatment. 👍 let’s see how it goes. I’ve done well past harvest but plants do end up looking sad. I’m in this to grow the best! Thanks for your input it definitely makes sense to me.
