Roots not growing on my seedlings..

I've got them under flo's 40 watt cool and 1 warm. They are on a heating matt, temp is 80, humidity 40-45, not over or under watered. One sprout out of 6 has grown to about 3-4 inches. The other 5 are still 1 inch, not growing, not dieing, just sitting there. I went and bought some fox farms soil for seedlings. I replanted them today. The soil I had them in was from outside and tested a 7 for ph. I don't get it.

what did you sprout them in?

Root temperature should be 65-75. Get rid of the heating matt. It may be whats stunting your plants development. Ive got a few runts myself that are probably 6 days behind the rest. I gave them a shot of Fox Farms Big Bloom and it helped some, but Im gonna check my mediums temperature to see if thats causing a problem. Good job at getting rid of the outdoor soil. Dont do that anymore obv

Moist paper towels inside a sealed ziploc bag . I kept under the heating matt. Soil from outside. An area near the septic tank and where nursery soil had been spread years ago. There were night crawlers in this soil. Soil maybe it was too rich? To strong?

What are you refering to when you say you have to check your mediums temp? Are you talking about the soil? Would Lowe's have a soil temp tester?

well if thats the case where is the nitrogen from???? and after 31 years of growing im telling you veg and bloom nutes run about the same price but in bloom several bloom booosters are ussually used which cost more.

I would say it's a combination of the soil you were using, and the heat. Take them off the heating pad - too much heat on those roots and you could cook them. Make sure your lights are close enough, within a couple of inches. Be extremely careful about giving seedlings any nutes - most folks don't start them until around three weeks of age, as plants younger than that are very sensitive and burn easily.

Its name is very misleading. Its NPK is .01-.03-.07

Its not really a "flowering" fertilizer. It has alot more in it than just Nitrogen, Phosphorous, and Potassium that is beneficial to the plant. Look it up and you'll see .

Lighthouse, I was referring to the soil when I said medium. I just use my digital thermometer. It has an attached cord I can insert into the soil and take readings that way.

Would Lowe's sell soil thermometer's you think? I need to get one to check the soil. If it's over 75 it's too hot right? Well I keep the temp at 80 in this little storage area. But I have my seedlings on that heating matt I was telling you about. This heating matt will stay I think 10 to 20 degrees above room temperatures. I've have them TOO warm, don't I ?

It probably wouldn't hurt too much if its over 75. I checked my plants and they anywhere from 74-78. Ive still got 3 runts though haha. 80 temps is fine, but ditch the heating matt. Its not necessary. The only time people use them is for germinating seeds and even then its not necessary.

Heres the thermometer I use.
