Thanks Con. A lot of what's here is about organics, but things like VPD or PPFD or calcium topics generally apply to all types of grows. You may have to slant it towards your style, but in general growing is growing.
Nice! alive is a good thing
. It's been a really busy week, I'll get over to your journal now that I have the time. I'm looking forward to catching up on everyones journal. 
I may resemble that remarkCongratulations on the retirement, second one right? Second verse, same as the first.
CongratsLife got busy... Hey Pal, I retired today so it's all about me. Set your life aside and serve me some plant porn damnit!!
I have a sneaking suspicion that you'll be able to sit still if your digging into that sativa stash you have more often 
.
Where can I download this app?So on the topic of VPD, who wants to see a cool thing? It's a 2 part post as it requires 12 pictures, so please let part 2 get posted before you post in between the parts.
Watch the leaf temps in the pic's, and once they reach 74 then watch RH to the end.
The intensity of light is what will raise leaf temps, and a combination of turning it up/down and plant height keeps it dialed in. As the plant gets taller it is identical to turning the light up. You may actually have to turn the light down from timecto time.
If you follow this your roots and shoots will stay ratioed properly if your soil and watering practices are solid.
Each picture includes a growth phase reference under the value being displayed, so please compare the value, and each picture is 1 week, so pic 1 is sprout time, pic 2 is week 2, etc.
So here it goes...
I think iv just found a free on google @Thirvnrob
Maybe...? again... sorta.... it might stick...Sooooo, then not retired. Got it.
Most definitely!Congrats
Myself I like 75ppm, but your brix are really high so what do I know
Ok so I'm thinking I may have picked up the start of a Mag deficiency. The girls had grown towards the light and the tops were probably into the 1200+ ppd range. There's a slight magenta hue at the tips and the saw teeth. It's only on the tallest colas and only the top 3-4 sets.
This is on the haze plant and she's been sucking down the Calcium so I'm thinking I may have to up her Dolomite maintenance dose a hair more.
If you use too much light you need CO2 supplementation. When a plant runs out of atmospheric carbon it stresses really hard and will sweat out magnesium. So that may be your issue. To be safe start with lowering that ppfd or strapping those colas down a bit.Also I accidentally ordered Glacial Rock Dust when I first bought Gaia Green and never used it. I've been afraid to use it because it contains no calcium and I know that it's best to use them both at the same time.
I got it off the Google Play Store, but I see it's not there now. Any 3 input VPD calculator will work.
This one looks good KalI think iv just found a free on google @Thirvnrob

Let @Gee64 check it out to make sure it’s legit, or try the same numbers Gee put in with he’s post , see if it’s the same
. Use the leaf VPD side. It will have the correct formula for what you want. It's good to see air VPD next to it, you don't ever want leaf VPD to be higher than air VPD or you get issues quickly. The stomata will shut down and transpiration will stop.
I've raised the light and backed off the intensity a hair.Myself I like 75ppm, but your brix are really high so what do I know

56-58%, I've been using the humidifier to keep it up
I Brixed her and she was 15 with a more defined line
Lol yep believe me I thought about this and also have the fan sucking the right direction.
Nope no gypsum but it's only a couple clicks away lol.
Good start.
There's your isdue. Get the dolowater. You will probably need it worked in regularly until harvest now.
Ixnay on the gypsum. I just asked because it could have thrown off your calcium to magnesium ratio, but if brix is dropping and your line is crisp thats your problem.
