Thanks for the input!doesnt look light burned. I dont know enough about soil to comment there but youre right you up potted a little early. youll see slower growth as the plant focuses more on developing roots. just make sure youre not over watering now because the pot size is much greater than the plants root zone.
if you can keep the humidity up around 60-65 that would be better than the 50 for this stage of growth. temp is good, 80 degrees sounds hot but with LED your leaf surface temp is actually lower than it would be if you were using hps so no worry there.
For humidity follow a Cannabis VPD ChartThanks for the input!
Ill get a small humidifer setup to boost up to 60-65% for veg!
Not too hot soil or bright light. Looks to me like you transplanted too soon and damaged the rootball in the process. Once they take hold they should be fine. I'd test the water ppm.Hey guys -
First timer here, from what I’ve read on the forums it looks like I have made a few of the common mistakes.
I started my seeds in paper towels, transferred to solos and from there into 1 Gal Pots. I think I was a bit pre-emptive in transferring from solo cups - but were here now!
When I transferred them I Used Coast of Maine Organic blend to fill the pots.
I believe the yellowing in the first set of leaves is from the hot soil? I also have a lot of LED for my 2x4 ( 7ft tall) tent so I’m also trying to avoid light burn.
I currently have my Optic 320H on about 20% light with a little bit more blue than red. Lux app on phone reading around 10k at plant height. Light approx 3 1/2 feet above plants. Running 24/0 in veg since I have No temp issues with the LED
Approx 2 weeks ago I germ’d these guys. (4 Runtz seeds)
Keeping temps between 70-80 MAX and RH holds between 50-60%
2 6” fans in each corner keeping a light breeze on the seedlings (both on low currently)
I have been watering when dry every 2-5 days with my Well water ( I live far outside of town and Tapped into a mountain spring. PH is just below 8. All I use is a sediment filter for my drinking water, so I figure I will also be ok feeding this to plants. )
Planning on some light LST to help increase yields on this first run- I’ve been debating if I should attempt Fimming/topping also but am leaning on just LST and a small amount of topping. Don’t want to screw things up!
Do you guys think I have this accurately diagnosed?
Hot soil & little too much light? Over next 2 weeks I should be slowing increasing my light output I think?
Thanks for any help or tips you guys may have! Really enjoying this experience thus far.
Sounds like you've got hard water and I'm pretty sure the Coast of Maine soil is calcium rich as well. Might get a calcium hardness test kit to see how much Ca your well water is adding; if it's over 100ppm it might not be right for that soil (or visa versa). Too much calcium can lock out other key nutrients including magnesium and potassium.When I transferred them I Used Coast of Maine Organic blend to fill the pots.

I did soak the soil before transplanting until there was runoff and then as delicately as possible took them out of the solo’sI think the irrigation is off a lil. Did you soak the soil when you transplanted?
When plants are that small, I always soak the soil til a very lil bit of run off then wait 4-6 days for it to dry back sufficiently, but the amount of time depends on multiple factors.
Next time wait till after 4 nodes or when the cup is full of roots. Wait until half way between waterings so everything comes out in one piece. Lightly prune a few side roots and place it in a pre watered pot with pre formed hole in the new container. Then don't water for a few days. When done correctly, there is no shock.I did soak the soil before transplanting until there was runoff and then as delicately as possible took them out of the solo’s
I struggled quite a bit keeping the soil “together” so I think growsince79 is spot on about damaging root balls.
ill check on the water ppm & calcium suggestions and get back!!
thanks everyone for the quick replies
Your soil is not hot. The opposite is the case actually.
Soil pH should be 6.3 - 6.5

Marijuana Watering, how media, pot size/shape and environment affect it
Ok lots of posts on how to water plants. So I thought I would put together a thread on how different factors contribute to different results that ppl see.

Watering SOIL
New Simplified Way to Water Marijuana Plants
The other day I had an idea and after testing, it works great. To know if you need to water, get yourself a soil meter. Poke or drill 4 holes in your pot 1/4 way up from the bottom spaced around the pot. Insert the meter probe into the hole and test for moisture. If its dry, then water SLOWLY...www.thcfarmer.com
Checked PH on runoff and input todayHello... Big time Mag def.
Check your pH to make sure you're not locked out.
