Got the EC under control, feeding 1-2 times per day. Once I have the EC of the runoff close to the nutrient solution I might skip the next feed and check runoff EC again.
I got fast growth in the first 24 hours after dialing in the EC and increasing the frequency of the fertigation. They are gaining speed.
Day 11-13 the WW is showing signs of heat stress (I think)

Grow Questions
Wontgiveup week 0 started grow question 2 weeks ago
How important is high RH and low VPD for young seedlings?
Using the mars hydro tsw2000.
-struggling to get to temp and RH that is recommended for 0.4-0.8 VPD.
If I go higher than 25% power on the light dimmer, my temps jump to 30 C and humidity drops to 45%.
The best I can do is 26-28C, 48%-55% RH. Is this ok for young seedlings??

Hi!

You can add a wet towel in to the tent and even better if you put it to a bucket filles with water. Also you can cut plastic bottle on half and place it as a dome but dont put the cap on so the air can exchange still

Is this heat stress? Young White Widow
Hey fellow gardeners,
Is this young White Widow showing signs of heat stress?
With lights on, my tent is a constant 26-28 C (79 - 83 F) and RH is 64%-74%.
And I do trust my sensors.
Mars Hydro TSW2000 turned down to ~40% intensity. Light was ~ 10” from leaves. Growing in coco.

I wouldn't worry about it, Cannabis plants can grow strange leaves at times, but I would try 24 inches at 75% as a first option to see if that helps, if you are really worried about the leaves.

@smoke24
MH recommends 24” for veg for that light but they also give measurements for PAR readings at different heights, and I mentioned I am at 40% intensity (because of high temps when running the light at 100%) which is why I was lowering the light.
When I had it at 35-40%, at 24” my WW was stretching....

Definitely light way too close, go with Smoke24’s advice!
