Plants all stopped growing and stunted

[Susie525]

I am a 2nd year grower. I have a grow room with a tent and a closet. I use Sunraise 1000 watt led lights 3 in the tent a two in the closet. My first two grows were fabulous. I had 5 seedlings and 1 in veg in this grow. Suddenly every plant stopped growing. I lost everything. I have studied in this until I'm crazy. The only thing I can come up with is our humidity dropped to 30 and stayed there this year. Nothing n the environment has changed. Growing in coco and use Fox Farms Trio. Can anyone help?

That's probably it humidity is more important than most people think. Check out this chart and link https://www.cannabissciencetech.com/...ion-operations

Edit = I like this chart a little better (2nd one)

I read that the plants veins pretty much seize up if humidity drops below 35 for a extended period

Welcome to GWE
Can you raise the RH, 30% is very dry and damages the leaves.

 

[SoOrbudgal]

Yes well that's not the big issue i think it's something else a pic of that grow would of been great.

 

[Rwise]

Ya, with pics its probably a PH issue.

Humidity does play a role on how fast a plant can grow and overall health but certainly does not stop it completely. I live in a desert average humidity is less than 20%. I don't use a humidifier or anything to increase Humidity except my plants.

Thank you for the replies. After reading the replies and thinking more on it I'm not convinced its humidity. I have always checked the ph and nothing changed over the last few months. I am going to get a new ph meter and check it against the one I have. For now I am not sure what else to do....

Susie525 I saw this thread when it was first posted and I was concerned about the growth of my second grow and the only thing I could think of was low RH which was ~30% sometime even in the 20s and since I got it up into the mid 40s growth is booming so I wouldn’t discount the RH thought yet.

Thank you. I haven't discounted the humidity. I had all seedlings and 1 in veg. What amazed me was that they stayed green. Just wouldn't grow. 2 inches tall and that was that. No growth whatever and the one in veg stopped growing as well. I got a new ph meter and the one I had read differently. So looking at both things. I am ready to start again. Wish me luck.
