VPD is my current struggle as well - my main humidifier for the room sits outside the tents - the CMH light is just so damn hot it makes it near impossible to get VPD right. I have actually thought about opening part of the door to my 2x2 and letting more air in to cool the tent more - i'm still exceeding 80 at times.

It sucks, but if you can’t solve the problem your plants will not be healthy, their radiator hose and carburetor is blocked...

Two variables in vpd:temp and rh%. 80 is not the issue (tho it is a tad high, imo, for cmh, but not for qb)...humidity is the more important issue...figure out how to get more moisture in the air. Maybe a vaporizer?

Was reading a little before I clock in . Says could be from heat in tents to plants uptaking more water or evaporate which makes the nutes concentration higher which makes ppm go up .my ph has been at 5.9-6.0 past couple days .

Temp directly effects both ph and ppm. Higher water temps mean less O2, more CO2. This will change ph and ppm.

Drinking will also change ppm, sometimes ph. Sometimes it's waste, sometimes its evaporation.

As long as your ppm and ph stay within range, you'll be alright.

Fluctuations are good as long you keep them in check.

yeah i was going to get a few things from amazon:

for DWC temps - https://www.amazon.com/gp/product/B01C6PE4G2/ref=ox_sc_act_title_2?smid=A2LCLHNZI16QFA&psc=1

for DWC pumping (thanks @Or_Gro) https://www.amazon.com/gp/product/B00APU2X0K/ref=ox_sc_act_title_3?smid=A2QDXNEULNPYX8&psc=1

for DWC tent humidity control - https://www.amazon.com/gp/product/B01FQKXRXA/ref=ox_sc_act_title_4?smid=A1RUFFFCQ74BCW&psc=1

for DWC tent humidity output - https://www.amazon.com/gp/product/B07KBRQN8F/ref=ox_sc_act_title_6?smid=A2KUZVNQ9LP7N9&psc=1
 
This is why I joined this grow with you guys. To learn this kinda shit. Iceman, moab... If you can get an evaporative humidifier at maybe lowes for $100, a good one, your issues will be solved. I got myself one and it controls the humidity soooo well, very powerful and consistent, not like the smaller cool mist humidifiers. A dehumidifier would probably be good too from what these guys say. The plants need less humidity in flower right?

Yes, less humidity.

50-60% through stretch, 40-50% after stretch to last 2 weeks, 30-40% last 2 weeks is what I prefer to boost resin levels and bract swelling.

dropping rh that low in the last month usually results in VPD problems and taco'ing leaves for me. I think this next grow i'm going to push 50% through the last bit of flowering

Thanks! I am gonna have to write this shit down. I have the equipment, now I know how to use it! Haha. Ive been running about 55-60% in veg.

I bought a pond fogger setup here:

I have this sitting in a 40 gallon recycle bin and it works fantastic for humidifying the room

best part? i fill up the tank about once a month (or longer, never shorter than a month) once we get into the dry seasons

I'm just saying the last 2 weeks.

This will be my first run with QBs from HPS, so I may have to adjust some variables as well to account for that.

They arnt going up astronomically. Just slightly. My water temps are about 73 and my tent temps are 79-80 . Rh is in the 40s I may get another humidifier to bump that up . Roots are growing pretty rapid now . Surprised I’ve made it this far .

No prob on the time...

but i’m the worst person to discuss nute deficiencies....i know zero...you know more than i do on this.

I see three issues, the brown spots, the discoloration, the drooping....

The only value i can add is that you have a major rh problem.. which i have learned: causes drooping and nute deficiency/lockout issues....basically the stomates on your leaves are stressed out severely, they control the pumping of vapor/liquid in the plant, they aren’t working propeely...you need to fix this, for sure...try to understand and start using proper VPD:

I’m sure 3rd monkey or S2C can help on the specific nute issues.

Lastly, make sure your ppfd on the tops is no higher than 600 in veg....

Got it! Thank you! My vod was golden before I added the 4th 96 now I’ve just gotta make Adjustments

Essentially the same thing in the tent pic above..i have a few standalone ones for shrooms....i find them hard to dial in, so interested in the other one for room-wide control....

Yup, very normal with the constant fluctuation of water level and gas exchange.

Your VPD is off, that's what we were talking about. You should try for 55-60% humidity if you can. The stomata are triggered by the blue spectrum to stay open, which will draw more from your res. If the ph is off, lockout. If you don't have enough micros to support their drinking habit, deficiency. If they go too long and pound water, toxicity.

Any medium under those rocks?

MC and RO water? Have you given it any calmag?

Most of what I see is ph related, other than the definite calmag issue, which could still be your ph. That's why you have some twisting on some leaves. Most of that spotting is probably magnesium, more so than calcium, but they run together, so you made the right call on the flush and ph reset.

As far as boron def, looks more like zinc to me. With RO water, it's easy to skimp on micros, so doesn't matter so much which it is, long as you get the ph straightened out.

I’m chalking it to PH and VPD I’ll get VPd fixed when I get home.

Yes RO water. I’m using S2C’s mastblend schedule for my hempys. Which has an all purpose and then magnesium sulfate and calcium nitrate as separate nutes. It’s a 3 part

All purpose
Magnesium sulfate
Calcium nitrate

I’ll tweak when I get home and make sure PPFD is in check as well thanks you guys!

Just for shits and giggles, check your runoff ppm. I'm not familiar those nutes, so I'm wondering if it could have locked out with the ph off.

Besides cal-mag, a big one is that qbs need to run higher optimal temps than hps...my guess is you already know this, but maybe others don’t....

details available via googling white led leaf surface temp....
