Hey Time! You might still need more nitrogen I had to give mine another half dose probably going to just keep using the grow fert every other water sense it has the same stuff as flower fert plus n not sure about yours though. I would just add more unless the tips of leaves get burned you don't want it to run out during the tale end when its ph'd water only.
Your at the stage where she is gonna swell, from the looks of her looks like some nice size buds you can tell with the bud at the v part of the branch how far out it is from the main middle stalk mine filled out from the center to that bud and then swelled up even more.
Totally normal to worry when leaves start falling off your plant luckily you caught it in time she will be fine.
Thanks bud.
Unless the plant tells me different I'll feed the same every watering right up to harvest.
I thought she stalled on me, just looking at her day by day. Couldn't see much change. But after looking at the before and after pics it looks like she's still trucking along.
