Ok, the plants are bigger now and they drink a lot more, so how should I approach toppings?
So far I could leave the res alone for 2 weeks just like it is. They drank about 3 gallons in a week at this point. Tomorrow I'm changing the res to bloom nutes, but afterwards, should I top off with RO water every few days, or RO+nutes to replenish?

Res change complete, and with my newly devised method, it took less than 15 minutes to do it all. Woot.
By the way, if you are a new grower and use Advanced Nutrients nutrients or additives, do not trust the indications. A half dose of just the basic bloom nutes (connoisseur A+B in my case) brought my PPM to the 900 range. Obviously a full dose is ridiculously over the top, I don't even understand why they allow this. A new grower without a PPM meter, if he followed the directions on the bottle to the letter, would completely burn and kill his plants. If you can't even trust the frickin' manufacturer's own label, there is a problem. Of course I knew this prior to using them because I had done my research and every forums warn potential users of this, but you shouldn't have to read forums to get appropriate guidance.
Their "pH" perfect formula though is pretty neat.
A week in bloom and they are growing like crazy. My screen is completely filled now (I'm leaving some room on the right for when I'll need a dehumidifier).
Once my screen is filled, I just let the plants grow vertically without any further training and let them be until harvest?

They grow so fast it's hard to keep track. Do you see these two new baby growths? The on e on the left was invisible to the naked eye 20 hours ago, the one to the right was a minuscule blip.
I've seen faster growth ever since I upped temperature to 90F.

Yup those little reddish hairs and white ones in the node above are little female pre flowers.

Different people do different things when it comes to their reservoirs. If you have two weeks capacity then you could just let it run for two weeks and then do a drain&fill with fresh. Some people extend by topping off with RO once the level gets 1/2 way empty and some top off with ppm/pH adjusted nutes at 1/2 to full strength. It all depends on what you're trying to accomplish...
The feeding schedule listed on nutrient bottles isn't for every plant nor for every growing system, they should be taken with a grain of salt. Personally I like using various versions of the Lucas Formula but, no matter what you use, the plants will usually tell you if you gave them too much or if they need something else.
If the screen is full and even there's nothing left but grow and harvest. If it's not so even you *could* move a few flowers around if that'll help.

Girls are drinking so much water I can hardly believe it but PPM remain stable so this means they eat as much as they drink, correct? So it's all good? 90F is definitely hot but there is no sign of them doing badly at all.
I've turned off the humidifier, and rH is maintained at 50%. My guess is the AC is keeping it down but I will soon need a dehumidifier when they grow more.
What rH am I shooting for in flower?

Like almost everything growing related, opinions vary but *I* like to lower humidity to ~50% in flower and drop that to ~35% for the last 2-3 weeks. This allows the air to stay dry enough to usually keep mold at bay during most of flowering and lowering it more at the end adds a little stress that is supposed to increase resin production as a protection from the dryness. Tropical landrace based strains might be able to handle more but that's just what I've used for years...

I had to move the tent in a new place and lost a foot of height because of it. The girls still have 2 feet or so to grow, but I'm afraid they might take too much room.
