grow it

from your only diary her grow conditions are off. The PH is too high and your lights seem way to close for 600 watts. I don't grow in coco, seems more of a challenge and learning curve. Keep it simple and follow the basic needs. Good luck

keep it healthy and stay out of its way. must be an autoflower... not technically week 9 of flower or it'd be much more ripe than that... i'd guess 28-32 days of flower. Figure it was in flower ~5-7 days before you saw any preflowers. It's a guess becuase human senses are not resolved enough to see the biology change, but once it starts growing those preflowers it's already been in flower a bit when you can see them.

Is it really week 9 of flower, she looks about 4 weeks in to me.just keep them going those 600w hps bulbs should do the trick, make sure they get fresh air or those lights might aswel be candles.. Good luck.. inbox if you need more advice

- increase Ca ppm - stop using veg fert - add some light (led lightbulbs 25-35w)

It looks like your plant is stretching a lot and the buds are developing quite airy. At week 9 of flower she should normally have denser colas, so the main reasons are usually low light intensity, too much nitrogen during bloom or stress from the environment. The pistils still look pretty white, so she isn’t ready yet – keep an eye on the trichomes with a loupe to know when she’s finished. Right now the best you can do is let her run her course and finish, even if the yield won’t be huge. For future runs it will help to train the plant earlier and keep the canopy even under stronger light so the buds can stack much better.
