Crazy looking seedlings

hunter · March 21, 2016

Posting a photo of my seedlings. These were started Feb 27. They've been under a new grow light since they emerged. I also have an oscillating fan on them. The temps under the lights without the fan reach 91F, but with the fans the temp drops to about 72F. The cotyledons are starting to yellow and fall off as the first seed of true leaves have appeared. They seem a little leggy to me and a lot of them are "twisted" looking. Not sure if that's due to the fan if there's something going on with them. I keep the lights about 1-2 inches above the tallest ones. Does it look like anything to worry about to you?

Not sure if this info helps, but the light fixture is a EnviroGro FLT46 4-Ft, 6-Tube Fixture, T5 Bulbs

Thanks!

What's your temps? At 24 days I'd expect more, but a lot of people do the cold grow thing and I'm sure they respond differently. The ones in the pic are 10 day old Delicious taken this morning. I'd say these are about average for me, and have been at about 78F since they were sown.

Thanks for the resized photo!

Temps have been in the low 70s under lights and with fans. Temps can reach as high as the 90s when the fans are off.

Not sure what the nightime temps reach when lights and fan are off. I'm assuming that it stays around the same as the rest of the house with is 65F.

Thin them or separate them. They are nearly four weeks old.

Agree pot them up and give them dilute 1/2 st soluble fertilizer. Then weekly fertilizer thereafter. I think they are stunted from crowding and lack of nutrients. Choose the best, replant them up to the first leaves in minimum 16oz pots or cups.
They should take off once potted up and fertilized. Turn your trays daily once potted up also.

Something doesn't make sense here.
They are over 3 weeks old? Yellowing cots and not growing as fast as they should. Hmmm....

Hunter, are you running that fixture with all 6 lamps on or 3? 1"-2" above the seedlings maybe too close for those HO lamps.
What kind of soil? Water source? Any fertilizers added?

hunter · March 22, 2016

Running it with all 6 on lowered to 1-2" above plants. Potting mix is Forest Farm Light Warrior. Water is just tap water that I let sit in an gallon jug. I have given them a couple half doses of fish&kelp.

I would try moving the lights back ti 4". You may be getting light burn.

Cool! Thanks for the help everyone. This is a new light setup for me this year. I'll separate, pot up, and move the lights up to 4" tonight.
