First time with seedlings and all the pics I've seen online show short stout seedlings but mine are really long with bent cotyledons. These are autoflower hybrids.
I started in rockwool. thoroughly rinsed it with PH'd water then set it on some hydroton and put the seeds in about 1/2way into the rockwool. Placed a semi-transparent cap on the container and put it on a heating mat in my tent. This was last sunday night. Took about 4 days for them to sprout (thurs night) and in the span of 1 day they stretched to the top of the lid so I removed the lid last night.
I noticed that one of the leaves was a bit yellow and drooping (first pic), so I mixed up a batch of GH 3-part nutes in 1/4 strength, ph'd it to 6.4, and poured it into the container so it covered the hydroton about 1/2 way (but did not really touch the rockwool).
Today, I noticed that the yellow-ish cotyledon had turned green again, but both seedlings have a single droopy coty. The first set of saw leaves are starting to grow out as well and I can see the tap root growing out from under the rockwool.
Concerns:
1. Is this amount of stretching okay? Can I give it a bit more support with careful hydroton placement when I transplant to my DWC or will this resolve itself?
2. Are the bent cotys okay? Or are there any corrective measure I should take now?
3. When should I transplant and should the DWC water have nutes when I transplant? (thinking about 1/4 strength, or is there a ppm/ec recommendation?)
Thanks!
