Ok good. I would use the molasses next watering, and add the dyno myco right before.

Can you remember what your air and leaf temps were, and what RH was at?

Also, are you still bottom watering, or has that been stopped?

I don't remember what the leaf/air/RH was at the moment and we're at lights out, so the IR gun is in the room. LOL
I'll be sure to get those tomorrow. It has a memory on it, so I can access that in the morning.
Two of the plants are now on complete top watering, the Goats.
The other two are getting 3/4 gallon top water, and the remainder is going into the bases.

Not sure what that question is about....if it was the RH and temps, I just posted about that. :)

Yeah it was. Ok no worries. Try to make a habit of looking at them. You need to be aware of how close you are on the 2 degree differential from leaf temp to air temp.

Regardless of VPD, if the leaf temp gets as high or higher than airctemp carbon assimilation gets restricted, and carbon is one of the big 5 for brix.

Less that 2 degrees difference means your light is too bright.
 
Rant begins. Feet stomping like a child. Fiery red face.....and yelling

I WANT THESE BUGS GONE!

Rant over
 
So when you do your checks, we all look for VPD and brix levels, but what you really need to look for is leaf temp differential and the state of the calcium line. When those 2 are good, then other adjustments can be made. Once those are good, then VPD and brix levels count more. But they are the immediate dangers you need to watch for 1st when testing.
 
Here is an example, and note the ranges on the bottom of the VPD pics.

Leaf temp is equal to air temp, no bueno.

Reduce light to get a 2 degree spread, no adjustments needed.

Now yours may not be that simple, but it could be.
 
Good Morning everyone!

Okay, It's pretty clear I needed to get the RH in the room back up. So, I got the bubbler going again this morning. Last night it was only 41% in the room. Weather is playing a role for sure, as well as the furnace on so much.

Here are a couple of the readings from yesterday before lights out at the 10 hour mark:

Ambient Temp: 71 F.
Ambient Humidity: 31.8%
Air VPD: 1.7
Leaf Temp: 70 F.
Leaf VPD: 1.6

2nd reading different plant:

Ambient temp: 82 F.
Ambient Humidity: 45%
Air VPD: 2.0
Leaf Temp: 77 F
Leaf VPD: 1.4

I am still working with getting readings correct. When I aim that IR gun at the leaves I can't tell where the red sensors are at, the light above washes them out. So I aim the best I can. Maybe I can turn the grow light off and just use room light for the time it takes to measure readings?

If you are wearing LED eye protection, it will make the red dot vanish.

I wasn't wearing any of that at the time. I did find a piece of black cardboard to block the light long enough to point the IR gun. So, I may just continue with that. :)

And what are you doing online? I thought you were taking a holiday somewhere? 😂
 
With your environment all over the map, the actual VPD's are in the ballpark. The plant VPD of 1.6 is right on the line of too high, but that 1 degree difference between leaf and air temps would be better at a 2 degree difference, which would drop VPD to a safer value. The other is in the safe zone.

They must be in 2 different tents?
 
Here are two BRIX readings I got yesterday at 10 hour mark.

Yeah, I just had to laugh at myself. Thought today was Friday, went in to mark something on the grow calendar and thought I had miswrote the days on the erasable calendar. LOL

More coffee coming up!

No, they are in the same room. The light is still angled to be closer to the flower girls and more above the Goats. So, I'm going to go in and straighten that out. I think that's what the difference is.

Calcium looks good, and you said your moisture was good, so that means O2 is good, so carbon is next. Is the one reading 7 the cold one with the high VPD?

The 11 is almost there😊. If it's the 1.4 VPD one, 1.4 VPD is a tad high for veg, so if you can get it to 1.2 she will relax her stomata a bit more and then more CO2 can get in, thus raising carbon input. Some liquid kelp if you have it will help destress them both.

The low reading one may also really benefit from the Dynomyco. They both will, but the low one likely far more.
