What could possibly be wrong here?

[lazerbrain]

2 week old White Widow Auto Flowers

I am using:

-4x4 Vivosun Grow Tent + 6" Exhaust and 6" Intake with Carbon Filters.

-Spider Farmers Sf4000 (450watt) LED at about 45% on the dimmer knob 23"-24" from the canopy of the plants.

-Water every 2-3 days with a Ph of about 6.5, using Aqua Safe to make tap water safe and 1ml per gallon with Micro (Advanced Nutrients).

- Sitting in 5 gallon buckets with holes through them and 30% perlite with 70% Miracle Grow Organics Container Soil.

-White Widow Auto Flower on 20/4 Light Cycle.

-Air Circulation on lower levels 2/10 on a 30min/30min Cycle to keep humidity within 50%-60%.

So why are my plants wilting and turning colors and not growing? Someone please f***ing help

Overwatered Could get by with less light too for now, especially since u got em half drowned. Don’t water em for 7days maybe more, during those 7 days research how to water cannabis seedlings.easy fix.

Could also be your soil brother!!
Especially if your adding more nutes to your water

Small plants in big pots are hard to water correctly.. Next time start with smaller pots, let it build a good root ball then transplant..

This. The Miracle Gro soil already has nutrients to last for a good amount of time. You don’t need to add anything at this point.

Just want to add also that seedlings as small of those for sure don't need that much light on them. I'd say a 450w led running at 45% is still 200w of light at only 2ft away. Seems a little intense for me. I have seedlings that size or new cuts, under barely 50w of led and they never look like they aren't getting enough light.

Too much light for too many hours..
Are your temps high enough? Like 80+ f.

All other points are likely too..

Also I have just looked up what AquaSafe is and I dunno man. Is your water really so bad to need it? Seems a little fishy to me (pun probably intended). I'm no expert on it by any means but it doesn't seem good to me (for plants anyway).

I guess I was just trying to go the extra mile with making my tap water safe. "Tap water often contains chlorine and chloramines, which are added during the water treatment process to kill bacteria and other microorganisms1. These chemicals can be harmful to cannabis plants, as they can cause root damage and inhibit nutrient uptake1. AquaSafe can help neutralize these chemicals, making the water safer for your plants."

They are Autoflowers, from my understanding you can run light anywhere from 12hrs a day to 24hrs a day. 20hrs a day seemed like a good idea. Temps range from 70-80.

I was told its better to start Autoflowers in their final home rather than transplanting because they don't have a very long lifespan and sending them into shock can really set them back and you get a lower yield.. but yes I am sure now that I have definitely overwatered them and looks like this whole batch just went downhill fast, all it took was overwatering them 1 time in the seedling stage and they are severely crippled now

I believe this is the most correct answer...The way these plants are curling downward, yellowing at the bottom leaves, the stems dont seem to be getting any thicker and there is virtually no growth happening anymore.. I got a little too excited and I watered the entire bucket when I was probably supposed to just water around the base of the seedling... they don't seem like they will make it past the 7 days at this point

Start in a party cup, they won’t stress with up potting, if your using miracle grow ( bad idea), you don’t need to add any nutrients.

Its the Organic Container Soil from Miracle Grow brand..but yes I am now sure that they got nutrient burned and overwatered/..probably will have to toss them and start from scratch. Autoflowers don't have a whole lot of time to get where they need to be for a decent yield..

What kind of soils would you recommend? Besides making my own.

Yes you can, if your environment matches the light intensity.

If it doesn't then you need to do lower the dli (less light, or less hours of light) or raise the temp to match the intensity .

70-80 is ambiguous.. night and day or just it ranges from that duringloghts on.. cuz they want to be 80 f and have the right rh .

They are tiny seedlings. They can't take high light at the best of times, and I'm not sure they're getting the best if times.

As I said, not dismissing all other issues, like over watering or hot soil..
But if your shocking them with an environment they can't take, they aren't going to drink properly and thrive

I found threw just a couple runs, have a spray bottle handy. I grew straight from jiffy pots to 5 gallon pots. You just need to stay ahead of the water dry off. Spray away keep that humidity up. Make them reach for the light now given freely. Less is more.

80 During the day, close to 70 at Night is what i've been getting. What do you recommend? I'm using a Spider Farmer SF4000 (450w) LED, How high should it be from the seedlings? I adjusted it from 24" back up to 30" from the top of the leaves just to be safe, I turned it down from 45% to 35% on the dimmer knob just to be safe as well... I'm being told this is a good range for seedlings that are approaching the 3rd week of life...my information could be wrong though..let me know what you recommend for Auto Flowers.. let me know what you recommend for light intensity/height and temperature. I'm definitely here to take advice.
