The Gee Spot - You Finally Found It

[Gee64]

Everyone take this opportunity to take a caffeine tolerance break and restock your coffee haha we've been hitting it hard the last couple weeks and Gee won't be telling us to get a cup of coffee so it's a perfect opportunity .

We gave been. Brix and VPD have become a hot topic all of a sudden.

Good morning Gee and friends,
Gee your suspicion was correct. Looks like my VPD is too high. Here's the results taken at 15 hours of lights on.

VPD is way too high.
I raised the lights some hopefully this will lower the leaf temps. I also bumped up my RH.

Where at?

Jersey shore

That's actually not too high, but a 2 degree offset would be better than 1.

I suspect that in the past when it happened, your VPD was much higher, and likely the lef temp was equal to or above room temps, causing carbon to get locked out, and combined with a high dose of calmag she ignited and exploded, doing exactly what @Odjob explained.... locking things out.

What stage/week are you at exactly? Sorry, I'm still trying to catch up on everyones journals.

Give her some fish water if you can, and if you have some liquid kelp a MILD dose of that too to destress her, but no more calcium until the refractometer gets close to being a crisp line.

If you have some zero ppm reverse osmosis water she would enjoy that too. It will help get her EC down until the calcium levels drop a bit.

With high ppm water like you have, you may never need calmag. The refractometer will tell you if you do.

Don't be sorry Geeman, we all appreciate your help.

Yea I agree I was lucky to grow up at the seashore.

The girls were started Nov 1st from seed. I lost a couple of weeks with slow growth leaving them in their 1 gallon pots too long. I still need to veg them a while longer to fill the 4x2 tent.

Have a great day

Ok, so still in veg. You are healthiest for that stage at a VPD of 1.2 or just under. They will grow roots better into the uppotting.

Somewhere between these 2 examples would be perfect.

So tomorrow, check VPD again, and pay extra attention to leaf temp. If you can get a 2 degree difference and end up between 1.1 and 1.2 for a VPD, your golden until flip. After stretch is done you want to be at 1.4 for the rest of the grow for your plant VPD while maintaing the 2 degree difference. In a perfect world you would just slowly lower RH to achieve it.

Lower it 1 to 2 points a week starting at flip to
achieve something close to this.....

Easy peasy, and that should recover them with better new growth, and maintain your awesome brix levels

Nice job on the brix btw, that kinda got lost in the convo. Very sweet, Congrats and well done!
