Seedling's first day under lights: first true leaves now yellow

I had started a seed of sannie's in a jiffy pellet with perlite underneath and I woke up yesterday to find a cotyledon rising up. I gave it a few hours of light, changed my mind and gave it 8 hours of darkness, then set it up for 24 hours of light under a single 24 watt cool cfl, a fan cooling its coils. I put the light quite close (little cotyledon's first true leaves appeared overnight) so that the top half inch of the plant was inside the cfl spiral, surrounded by light. I returned 10 hours later and found the true leaves had grown, yellowed, and curled down and the cotyledon leaves were lightening in color. The tiny pellet was dry so i watered it. Then, I decided to transplant it, and I exposed the raw white taproot (pulling it out of the perlite) to a a small bit of air, light, and time before transplanting it into a pint of foxfarm ocean forest surrounded by an old, still wet pellet leftover from a prior germination attempt.

The plant is under the cfl again, but not within its spiral, perhaps a few inches away. i watered the pint until it drained out of the bottom.

any advice would be much appreciated

Hate to be a downer, but the chance of it recovering are slim to none. I did the same thing with mine not too long ago and they never recovered. You can't let them dry out this early in the stage and letting it get that close " Especially inside it" to the light, probably got burned pretty good. If some how it does recover it's almost not worth even keeping because it is going to grow very slow and immature comparatively. If a plant stresses out this early in life not a good thing.

If this is your only one and you won't have another one anytime soon than by all means let it grow.

I think you may be out of luck. FFOF can be too rich for young clones and seedlings especially if the roots are not will established. I learned this the hard way and now mix with peet 50/50.

Thanks for your responses. I think it's looking just a little better - the leaves have lifted up and the plant has grown a few millimeters since the trouble began - but how do you think it looks?

it's now 3 hours since my last post and i decided that I had probably overwatered this evening, so I moved the plant into a new pot and added a good deal of perlite to the soil mixture so the plant could get some air (its stem is half purple).
since then I think those yellow leaves have grown a little. She is green in the center, and green on the tip, but only yellow in the middle.

Whether light burn or lack of water and air or lack of nutritious soil I cannot say for sure. . . wish i were fooling around with bagseed right now!

I woke up this morning and the seedling was looking good! Nice and green again, all of the yellow almost gone. She didn't seem to need water yet. That was a few hours ago. I checked on her just now and she is lying on her side. What could have gone wrong? Off to search the forum for answers. I gave her a little drink and will wait and see.

Ah, I think when I set the soil out in its new pot I did not pack it tightly enough so that when it dried, there was not enough support for the young stem. I buried it a bit deeper and added a little water to help make the soil compact. She's standing upright and looking good. Hopefully she survives all of this early ill use!

Titycaca, I think you are totally right about it being light burn.

Oldandbold, I think the FFOF was part of the reason my first seed (another sannie but feminized sativa delicioso strain) did not make it and has not recovered. I shall go with light warrior if i ff again, or take your suggestion for peet. In fact, for this one I have a peet pellet that started the seedling, a second peet pellet for it to grow into, and then the ocean forest stuff for it on the outside of that. My hope is that it will take what it needs from the ocean forest when it is ready and not before. Fingers crossed on that one.

Ah...

Hallelujah!
I think those who said my plant was dead or destined to grow slowly may be joyfully proven wrong Thank you for keeping my hopes low! Better to look death straight in the eye, I think, and thank you for participating in this with me. I am happy to report that it is now day 4 under lights (one full week from the time i put the seed into water) and the 2nd set of leaves are coming in a nice healthy shade of green The first set of leaves that got light burned have all but fully recovered, and just a bright yellow mark on one leaf remains to attest their rough beginnings.
The cannabis plant she is strong, no? A little light burn is nothing to a light loving plant! But now I'll keep my tender seedlings more than half an inch away at least.

Looking good after reading all it went thru.The ROCKY of the mj seedlings!

Looking good. Are you going to be doing this whole grow cfl or are you gonna switch to HID lighting?
