Sorry! I thought it was soil. My bad ...
Then yes, that is a good pH for that medium. I use straight Pro-Mix HP and I'll pH the water down to 6.0
Plant is overwatered! But the soil is now dry?

Looks like light intensity stress to me and probably bad watering practices like other suggested.
I wouldn't focus that much on VPD. While it may give you some reference point you can grow A+ medicine outside "optimal VPD". Keeping RH down really low during flower may even be necessary in certain situations.
Problem with VPD is that it doesn't take radiation in to consideration. It's a good reference point but nothing set in stone so to speak.

Whelp, I've watered it. Got about 10% runoff as usual. Fingers cross but I don't have high hopes. Any tips on what to keep my environment at? Like I said earlier im running 25°C average for temps and 25% humidity to try and coax them to transpire the most water. Is too low humidity bad for water transpiration?

25% RH is really pushing it. I would try to up that to 50%. Plants can tolerate more light intensity with higher humidity.

Weird right?, asking for help and receives straight forward suggestion on a solution. Maybe he forgot to take his medicine this morning? What an ass yeesh

In most situations yes. Some time it's necessary and there's difference between running salts and organics.
But most times it only causes more problems because the soil is already amended and pH buffered, with alive well fed microbes in the soil it should not be needed at all.
I think in terms of what's in the medium not just focusing on what I'm feeding. Cheers!

Yeah at the start,ea bag of promix has different pH.After a few feeds the salt builds up and ph changes.Some bags can be really low ph right off the bat.You really need to check ph in runoff,not 100% accurate but gives you an idea.Promix likes a little higher then coco.

Ok if it's completely dry this is when you water then wait for the exact same thing and repeat

I've taken all your guy's advice, raised the humidty agaim and watered her back in. She's doing a lot better. This is only 3rd grow and I'm still learning daily. Thanks guys

Dude just saying in general if you wanna be 100% sure, wait for the top 1-2 inches to get BONE dry plus some plant wilting but only when the surface is bone dry.
Thats without a fan hitting the soil surface directly. If you got a fan on it, it seems like its dry and thats when problems start. Plant looks good apart all that though

I heard when your plant wilts at all you'll sacrifice end quality. I definitely haven't overwatered since. It ended up being slight overwatering and major light stress! I've been watering when the first inch is bone dry. Thanks for the advice!
Plants are doing very well now since I've dimmed my lights more. Here's some pics
